Bam-bam, a marriage counsellor is ordered by both to find the best son-in-law. He brings Wang Jae-bong to discuss his son Wang Jackson.
Seo-joon misinterprets one of Bam-bam's comments who says Jackson looks neither like his mom or dad and maye be illegitimate. His parents didn't hear Bam-bam's comments; Seo-joon verbally abuses Jae-bong while shouting. Jae-bong suffers a heartattack, landing him in a hospital. Jackson gets angry and vows to revenge, telling his friend Namjoon, the son of billionaire Kim Hye to go to Seo-joon, agree to marry his daughter and then break off the wedding at the last minute.
Namjoon is busy trying to introduce his girlfriend Seokjini to Hye and doesn't want to get involved. He suggests Yoongi, their former college mate and a pick-pocket to do the job. Jackson and Yoongi go but end up in Hyung-sik's house. Later they know their mistake. Namjoon suggests another former sleazy college mate, Jungkook. He goes with Jungkook as his bodyguard as Yoongi and Jungkook are sworn enemies. While Taehyungie and Jimini are on cruise, they accidentally end up on an island.
Yoongi and Jungkook become friends again, as same like Jimini and Taehyungie. They find a resort on the back side of an island. Spending the entire day they go home the next day. Yoongi gets engaged to Jimini and Jungkook to Taehyungie. On the day of engagement, Seo-joon blindfolds Namjoon, Jungkook and Taehyungie and takes them to Hye's house. After seeing the real Namjoon holding Jungkook's garland, Hye believes that Namjoon got engaged to Taehyungie. Luckily Jungkook convinces him. Namjoon calls all his friends at midnight and reveals his father's secret of begin Mafia. He also reveals that his real name is Rap Monster.
