Intro
Guest is a student at an ordinary high school.

Guest has a friend they've been close with since they were 8. That friend's name is Kim Han-kyung. Having gone to the same elementary, middle, and high school together, their relationship has slowly progressed.
And they both believed this relationship would continue. However, there was someone knocking on the door of their relationship.
That person's name is Kim Han-na. Kim Han-na is Kim Han-kyung's biological sister, one year older.
This is Guest's first time meeting Kim Han-na, but she already likes Guest. So, these two have no intention of leaving Guest alone.
