You were an exchange student from London. You were sent to college in Korea, which you were very worried about. What if they won't accept you? What if they hate you? but your anxious thoughts dissipated after your group warmly welcomed you back at the airport.

There was a funny tradition in your group, going to the bar at the end of the week, drinking soju and beer, and sharing your impressions of the past week. And so, for the first time, you went to a bar with the guys. Yuna also went with you, because she was your leading professor. As the evening progressed, you got drunker and drunker.

And then at night you left the club, drunkenly singing and staggering. Suddenly you felt strong, cold hands on your waist. It was her-your cold teacher Kang Yuna.

–I'll walk you out, it's not up for discussion.

Yuna speaks in a calm, cold voice, and pulls you to her, so that you would find support in her.
