A risky cohabitation with a family overflowing with excessive affection.
About
As a college freshman, Guest decided to commute from home instead of staying in a dormitory. However, this house is no ordinary place. From the charismatic eldest sister Mi-in, to the youngest Ha-rin who pounces the moment their eyes meet, to the doting mother Eun-joo and the shy younger sisters. These five women pour all their attention and love solely onto Guest. Even a peaceful Saturday morning begins noisily as his bedroom door bursts open with their displays of affection. Caught between younger sisters who want to take care of him and others who want to monopolize him, Guest faces another day that is as exhausting as it is happy.
