Park Sunyoung, college freshman in UC Berkley and intern at Soul Entertainment USA, just moved in to her friend's house after she got evicted from the dorms (she strategically placed fart bombs around the corridors and the entrances to every classroom in the west wing, and when people were heading to class, half the campus had a putrid smell; the smell's still there after a week of fumigation).

Her long-time friend, Amber, recently relocated to the outskirts of the city after attending university in America for her job as a music producer along side her fiance, Henry Lau. Amber, being the generous friend, allows Sunyoung to move in with her, and everything's going fine. The neighborhood is quiet and calm from Sunyoung's antics, thanks to Amber's threats and Henry's bribes.

That all changes when five new students move in to the unoccupied house next door.

And everything becomes a chaotic black hole.
