She was just a girl. She doesn't want to get hurt. She was afraid of getting hurt. So she tried her best. She did everything to kill all the strange feelings in her heart. She promised not to fall in love. She caged her heart.
However, someone still managed to break in. That guy made her fall for him. He keep on getting close to her, not knowing what kind of torture he brings. The girl keep her distance, but the guy never let her go away.
The girl being naive, silently fell in love with her innocent feelings. She was quiet unaware of how she feels. She is in love yet she didn't even know it.
She took her love as an affection for a brother, misunderstanding her own feelings.
She eventually let the guy by her side because she thought that she was only yearning for a brother.
Time passes like that, until the guy get her own girl.
The girl still didn't notice her feelings, still smiling. She was hurt, but she didn't even understand why. She just keep on enduring everything thinking everything will eventually fade.
Until one day, the girl can't find the boy at her side anymore. Her heart broke like a fragile glass. And that when she realized that she was in love.
But her realizations were too little too late. The guy is already happy with his girl, and forgotten that once, a fragile girl existed.
The girl was left behind, with only the faded bittersweet memories in her heart.
