*Tut-tut-tut! tut-tut-tut!*

"Arghh f*** this alarm!" Sun-gu exclaimed,"Oh s*** it's already morning. Crap I'm gonna be late."

"Big brother wake up!" Ji-yeong shouted while opening the door and jumping unto his brother and hugging him tightly.

Ji-yeong is Sun-gu's sister whom he loves very much.

"Sis thanks but can you please let go of me now?" He asked already looking pale and gasping for air from his sister's tight hug."Thanks."

"Big bro, it's my first time seeing you wake up early!" She exclaimed looking happy that he woke up before being late.

"Really? Well I think this is the first time I've seen you so excited on the first day of school." He replied while standing up quickly, "Sis, I'ma go get ready now. Please leave the room."

"Ok, but first kiss me on the forehead." She said making a cute face, "Please!"

"Fine. You win, come here." He said with a face that lost hope.

*Mwah*, "Now that I've done what you want, let me prepare in peace." He said.

"Okaaaay." Ji-yeong happily obliged and left the room.

"I guess I've spoiled her too much when she was young." He thought while changing his clothes, afterwards he tidied his room a bit and headed out of the room.

"Sis I'm ready, let's head out." He informed while walking down the stairs and headed to the door.

"Big bro are you not gonna eat breakfast?" She asked.

"Nope ,I'm gonna be late if I'll stay another five minutes."

"Fine you meanie. Just let me grab a toast so that I won't have an empty stomach." She sulked. She grabbed a toast and then sprinted toward her brother.

"Let's go." She said nibbling the toast as they walked out the house and went to school.

"Hey sis, what do you plan to do later at lunch?" He asked.

"Nothing much, just gonna eat at the café."

"Can you accompany me for a bit later?"

"Well, only if you make me some dinner tonight."

"That's fine with me but don't go back on your word 'kay?"

"Don't worry, I always keep my promises."

"See you later at the café then."

"Yup, take care bro. I'ma go ahead." She informed with a cheerful face and then ran towards her classmates.

*Sigh*, "I wish that cheerful girl will take care of herself, afterall she's to naïve." Sun-gu tought to himself.

"Hey Mr. Siscon, remember me?" someone asked as he covered Sun-gu's eyes.

"Of course idiot." Sun-gu greeted with a smug face as he turned around, "Long time no see Kim Lee-woo. You really should get a proper girlfriend you know and not waste your life playing eroge and creeping up on young girls. That could get you arrested."

"Says the person that has sister complex." Lee-woo replied.

"Well atleast I got someone to love, how about you? Do you have someone?" Sun-gu argued.

"Fine you win this time." Lee-woo replied, "Btw, did you know that there's going to be a new student today?"

"Nope, how are you so well-informed anyways?"

"Connections duhh."

"Oh I forgot your father is one of the founders of this school."

"Anyways let's hurry up to school so that we won't be late. Oh and also the new student will be a girl so you better prepare yourself 'cuz my father told me she's pretty." Lee-woo informed while walking faster.

"Nah, my sister is the only one I need in my life." Sun-gu replied.

"Make sure you won't regret that decision bro." Lee-woo said with a concerned face," I heard she was quite beautiful and charming, who knows maybe she'll be on our class."

"That'll never happen." Sun-gu argued.

"Let's just see for ourselves." Lee-woo replied with a curious face as to what would happen later on if they do meet.

"Come on let's hurry!" Sun-gu exclaimed while sprinting.

"Fine, wait for me." Lee-woo said while catching up.

Sun-gu and Lee-woo continued to sprint to the school gate.

"First, hehehe." Sun-gu said while gasping for air

"How do you run so fast anyway?" Lee-woo asked also tired.

"You're just slow." Sun-gu replied almost done catching his breath.

"You really don't know how to hold back on your friends dont you?" Lee-woo stood up straight not looking pale anymore.

Sun-gu then raised his hand and opened his palm amd said, "The winner's prize."

Sun-gu and Lee-woo had this contest to race to the gate and whoever finishes first gets a prize from the loser.

"Fine I'll give you my card today, just don't spend more than 1000 won okay. And also don't lose that." He said with a forced expression.

"Don't worry, I'll put it it my wallet." Sun-gu teased.

"Wait, where did my wallet go? I knew I put it in my pocket." Sun-gu gasped.

"Let's look around for it" Lee-woo suggested.

"Ok let's hurry up." Sun-gu replied trying to keep his composure.

But before they could walk out, the guard yelled, "Hey you over there." Pointing his finger and looking at San-gu.

San-gu looked over and replied, "Me?"

"Yes you, is this your wallet?" the guard asked.

"Yes that's mine thank you very much." San-gu exclaimed, happy to find his wallet.

"You should go thank that girl over there." the guard pointed at a girl that was on her way to the school building, "She gave that saying it was yours."

"Yes I'll go thank her now." San-gu then ran leaving Lee-woo behind.

"Hey!" He yelled to call her but the crowd made her uneasy to catch up to. He ran but to no avail he didn't get a chance to say "thank you".

San-gu then stopped chasing after her went to his classroom. He then seated and thought, "Thank you whoever you are."

"Good morning class." Professors Choon-Hee greeted. Professor Choon-Hee was their homeroom teacher, she is a young and beautiful teacher. Even her co-workers stop in their tracks to marvel at her beauty.

"Before we start our classes, there is someone I'd like to introduce. Your new classmate Ms. Eun-ju. Ms. Eun-ju, please introduce yourself." She instructed.

"My name is Choi Eun-ju, I hope you take care of me" The new girl said, clearly confident and cheerful.

"Wtf the transferee really did become our classmate, she's so pretty." Sun-gu thought to himself, "Nope, stay calm you still have your sister to take care of, there is no space for romantic feeling for others."

"Ok now that miss Eun-ju has introduced herself, someone has to show her around, Sun-gu show her around will you? And also miss Eun-ju you may sit beside Sun-gu over there." Professor Choon-Hee instructed as she pointed out the empty seat next to Sun-gu.

"Hello. Sun-gu right?" She asked.

"Yes, it's nice to meet you Eun-ju." Sun-gu greeted politely.

"Likewise, I hope you can show me around. Are you free during lunch?"

"Yes." He said while wondering why there was something bothering him.

"Okay now let's start class." Professor Choon-Hee said as she started to write something on the board and started her lesson.

Sun-gu often doesn't pay attention to class and all he does is watch what's happening outside since his seat is near the window. As he continued watching the scenery of the school, he remembered he had plan with his sister during lunch.

"Crap! I remember I asked sis to accompany me because I wanted to show her something. Noooooo! It's almost lunch. I need to find a way to explain that I have plans with my sister." He thought, "But how can I do that without making Eun-ju dissapointed? After all, I also don't want a bad first impression. Arghhh!"

"Oh wait a second I can do this two birds with one stone." Sun-gu tought figuring it out. "With this I can definitely keep both promises."

Although he isn't really that smart, he does have some talent especially when it comes to calculations and planning. He thought that maybe he can do both at the same time as long as there is a specific time schedule and a proper moment in each scenario that can make him escape.

Waiting for the time to reach 12:00, he thought of every option to maximize the time and backup plans in case his main ones fail.

*Ring*

"12:00 o'clock let the plan begin." Sun-gu tought as he begins his plan.

"Ready to go?" He asked while aproaching Eun-ju.

"Yes!" She replied cheerfully, "It's my first time having a guy show me around."

"Why's that?" He asked as they headed out of the classroom.

"Well apparently, I've always went to an all-girls school."

"Oh, why did you decide to transfer here then?"

"Because of my parents' job."

"What does your parents do anyway?"

"My father is a lawyer while my mother, a-about her..." She stammered and stopped her tought.

"Oh it's fine if you don't wanna talk about it." He butted in, Realizing it was a sensitive topic and he probably shouldn't push it further.

"Oh here we are. This is the library, our library has a lot of book collections from atlases to documentaries." He tried to explain it in a way that can entertain her.

"Wow this library is huge! It might even be bigger than the one at my previous school." She moved towards the center of the library and was amazed by it's size.

"Well this is just the first place, there are more places here. Shall we continue?" He asked

"Of course!" She exclaimed quietly knowing it was the library.

"But before that, can you let me go to the restroom? My stomach kinda hurts." He lied while making his face look sick.

"Of course, I'll just continue to look around the library and wait for you." She continued looking at him concerned.

"Then I'll be back in a bit." He reassured and quickly ran to the exit.

Sun-gu then left quickly and went to the café and met up with his sister.

"Hey sis sorry for taking too long, I kinda had a bad stomach." He explained.

"It's fine, btw where's that pervert Lee-woo?" She asked wondering why he was alone and didn't bring any of his friends.

"Nah I went here by myself, after all I have something to show you didn't I. How about you, where's your classmates?"

"Well I said I was going with you so here I am." She reassured.

"Oh what are you going to show me anyway?"

"It's a secret" He teased.

"Well because of you being late, I haven't ordered yet. So what do you want?" She complained

"Well I'll have what you'll have." He replied confidently knowing that when it's lunch time the café is usually full.

"The line is too long so you better not complain if I'm gonna take a long time."

"Ok." He replied with a confident face knowing his plan is working.

After seeing his sister fall in line with a lot of people before her he then quickly left the cafe and headed back to the library to accompany Eun-ju to the next place.

"Eun-ju hey over here." He yelled.

"Oh Sun-gu is your stomach feeling better?" She asked out of concern

"Yes it feels a little bit better." He replied, "Let's continue next we are gonna visit the gym then the pool."

"Ok sounds fine to me." She agreed with a smile on her face.

They then started to walk to the gym and continued to chat.

"Hey Sun-gu do you remember me?" Eun-ju asked.

"Nope, have we met before?" Sun-gu replied with a confused face wondering if they ever met.

"*Sigh* Guess not, remember earlier in the morning I was the one who returned your wallet."

"Oh I remember now your that girl who didn't even tell her name. Thanks a lot though you really helped me a lot cause of what you did." He said gratefully, "But why didn't you say who you are to the guard, atleast in some ways I can repay you."

"Well it's not like I was looking for a compensation or anything, I was just doing the right thing." Eun-ju said cheerfully.

"Can I treat you sometime? You did find my wallet so the least I can do is repay you." He asked out of gratitude.

"Well it's kinda akward to accept after all I do it without thinking of a reward. " She replied.

"But I want to repay you somehow." Sun-gu insisted.

"Fine then I'll accept."

"Later after school at the café, deal?" He asked.

"It's fine." She said as they arrived at the gym.

"Ok then plan continue." Sun-gu thought as he started to speak.

"This is the gym. This is where we gather during the assembly and of course during events." He explained, "Though it's usually used by the basketball club after school for practice."

"Not bad." She replied, "It's so spacious. Why is everything in this school so big."

"Of course this school is the 3rd biggest highschool in this country after all." He explained, "So it's not much of a surprise."

"Well I guess." She replied as she then took a look around. And after she was satisfied they then left and headed out the gym.

They continued their walk until they headed near a bench, Sun-gu stoped and asked, "Can you stay here for a minute?"

"I can, but may I ask the reason?" She replied.

"My stomach kinda hurts again."

"If you want I can accompany you and buy some medicine."

She moved closer and placed her hand against his forehead to check for his temperature. Sun-gu took a step back and said, "Nope it's fine I'll be back before long."

"Ok then." She said with concern.

Sun-gu quickly ran to the direction of the café. When he got there he immediately sat on his previous seat. After her sister finished getting their meals she returned to their seat.

"Hey bro where were you?" She asked, "I noticed you weren't on your seat before. Where did you go?"

"Just took a number two hehehe." He laughed it off.

"Well you sure did take a while." She pointed out

After that Sun-gu didn't reply and continued to chat and eat with her sister. After a while he then distrupted the peaceful time and said.

"Sis the truth is I was supposed to be a guide to the new tranfer student, but I didn't wanna miss this time with you. If possi-"

"Yep you can continue your tour and also go for her if you like her." She butted.

"Wait what? What do you mean go out with her? And how did you find out that I was her tour?" Looking flustered and confused.

"I'm your sister aren't I?"

"Well guess I couldn't really hide it from you." He played it off.

"Now what are you waiting for mister rude tour guide, go continue."

"But how about you sis?"

"I'm fine." she replied, "Now go."

"Thanks for understanding sis."

He left and ran towards the area where he left Eun-ju only to find out she was being ganged up by three guys.

"Hey!" He yelled, "Go away from her."

"Oh yeah, well if it isn't little Sun-gu the siscon." One of the thugs replied.

"I said get away from her or else-"

"Or else what?" Another thug butted and cut his sentence.

"Wanna fight?" Clenching his fist getting ready for throwing a punch

"You think we're scared of you just because you're a skilled fighter. Well screw you there's three of us." The leader replied also getting ready for a fight.

But just when the fight almost began someone spoke and disrupted the dispute.
