Hanjoo Yeo, a reserved and introverted student, has been hopelessly in love with the most popular guy in college, Chanyoung Choi. Despite the unrequited love and constant feelings of regret and humiliation, Hanjoo finds himself unable to end the relationship. But when his father remarries and introduces a stepbrother, Jihyun Yoo, into the mix, strange things start to happen. Nobody seems to notice the tall and handsome stepbrother, and soon, things begin to take an unexpected turn.

Seo Yi-sol, the older brother who lives with him, is the only one who has not been able to enter his room. After 6 years of not being able to cross the line that Ga-eul drew, Yi-sol wants to cross that line.
