Sa In is a 22 year old woman studying to be a lawyer who lives in an old run-down room in a small apartment building in Seoul. Because most of her money from part-time jobs go on her school and to look presentable, she lives by eating ramen and rice. But what happens to her when one day a tall man comes flying through her wall and the buildings owner says it'll take about a week to get the wall fixed leaving Sa In and the man living basically together?
