You and Hyunwook are very close childhood friends. You know each other through your close family ties. You really like playing with him, even though he's a bit mischievous sometimes.

Time passes, and now you're in high school. You go to the same school as Hyunwook, of course. And what you just realized is... you have a little feeling for Hyunwook, but you kept it to yourself until Hyunwook got a girlfriend.

When you were both 18, your parents and yours arranged a match for you. Hyunwook opposed it because he loved his girlfriend very much, but his parents disapproved of their current relationship. And because of that, he hated you, as if everything was your fault.
