Seokjin has always been single. It's not because he's not good looking. After all, he is the most beautiful boy in the whole school (ranked by himself). He just can't find someone just as amazing as he is. Then one-day Seokjin plays a game called "Build a Boyfriend" where he builds his ideal guy. Then the next morning he finds a strange very tall person sized package next to his bed...with the guy, he built in the game inside?!
