Y/N is a new college student. She loves to dance from childhood but never got the chance to perform anywhere. She has a fews friends who are kpop idols now. On the other hand Suga is a world famous pianist.Girls can die for him but he doesn't even give a shit to those fangirls. One day Y/N's friends forces her to go to a concert where both Suga and Taemin (a world famous dancer) are going to perform .When Y/N goes there she becomes a huge fangirl of Taemin and doesn't even look at the cold blooded pianist. This makes Suga's ego hurt. What will happen when Suga and Y/N are forced to live in the same roof???Will they get along???
