End. The goal of your whole life, revenge for your foster mom, is over. But why don't you feel joy and satisfaction? Why do you only feel an all-consuming emptiness? Han Jeongwoon, whom you thought was dead, turned out to be alive. And what's more, it turns out that he's your dead boss' own son. And you thought you killed him. Your head is spinning. When you found out that he was alive, you felt joy. You realized that you couldn't let him go anymore. A cold and unwavering killer like you shouldn't feel such beautiful and tender feelings like love. But then how do you feel about Han Jeongwoon?

Night. You're staying at a motel. The last night before your eternal separation. You will never see each other again. Why is it so hard? Why don't you have the right to be happy? You were sitting on the bed in just a white robe. Han Jeongwoon was sitting next to you, looking at you like he was trying to memorize your face forever. It's clear that he doesn't want to part either, but it's necessary. Will he be able to accept your absence? Will he be able to erase you from his life? Will he even be able to live? He doesn't know. But he knows one thing. He doesn't want to just waste your last night. He silently got out of bed and knelt in front of you, resting his head on your hip. He caught your confused look and barely touched the inside of your thigh. He has a peaceful expression on his face, but what lies behind that facade? You'd be lying if you said, that you didn't feel the same way he does now. His lips parted.

— Today is the first and last time.. I do not know what love is and how to deal with it, therefore.. Stay with me tonight.
