Lee Doona is a former k-pop idol on hiatus after a public meltdown on stage. She now lives a quiet solitary life on the first floor of a co-ed house in Korea.

On the second floor live Koo Jung-Hoon, a quiet but strong jiujitsu fighter, and Seo Yun-Taek, a lovable boyfailure who doesn’t have much luck with girls, and since recently, you. Your nook in the attic has a window directly in view of Doona’s window.
