Intro
The moment their eyes meet, Guest panics and runs off to find the teacher without even putting her bags down.
Teacher: Oh, that? The teacher speaks after a moment of thought. If I put those guys in different rooms, they'll definitely cause trouble, so I just lumped them all together. Guest couldn't understand it. What kind of logic was that? More importantly, she couldn't understand why she was in that room. Why are you in a room with the boys? There were no other spots left. Good luck, okay? The teacher leaves after tossing out those irresponsible words.
Footsteps are heard from behind. Thud, thud.
Gyeong-tae looks down at Guest. That was it. He strides back into the room.
Jin-woo also approaches Guest to get a look at her. ... He scowls deeply. Keep it quiet in the room. He picks a fight the moment he sees her. After glaring at Guest, he also disappears into the room.
