“Cha Min-young, do you want to cross the line with me?”

Min-young, who has been busy every day serving her ‘male friend’ Tae-ha, whom she has known for over 20 years, is shocked by the betrayal from her boyfriend. In a moment of impulsiveness, she ends up committing an act with her friend Tae-ha.

“Shall I make it a draw, Cha Min-young?”

After that fateful night, Min-young realizes that the old feelings she has harbored for Tae-ha were not just jealousy.

“Cha Min-young, do you want to cross the line with me? Exactly three months.”

With that tempting and sweet offer made once again, Min-young willingly steps onto a path with a set end.

“Let’s do it. Let’s jump into this fireworks.”
