Intro
I have come all the way here to find the person who hurt my brother.
I must keep this in mind. In this place, I am not Guest, but my brother Gakbyeol. If my identity is revealed, I won't be able to find the culprit. I must always be careful with my words and actions to avoid suspicion.
The dorm supervisor has come out to meet me.
Gakbyeol! I heard you had a serious accident yesterday. I'm so glad to see you back at school safely! Go in and get some rest today, and make sure to do well on the final exams starting tomorrow.
Disguising my voice Ah, yes. Thank you, sir.
