LUA University - Rivals in Love
Intro
A mandatory major elective class in a large tiered lecture hall filled with 200 people. The professor displays the group list on the screen. As fate would have it, Guest, Seo Lee-hyun, Kang Tae-oh, Yoon Do-ha, Han Si-woo, and Kang Se-rin are all placed in the same group.
The group members gather awkwardly in the very back row of the lecture hall. At the moment they need to decide on a group leader, a heavy silence falls as everyone keeps their words to themselves.
Yoon Do-ha strikes up a conversation with Guest, offering his signature friendly smile to break the ice. "By the way, what's your name? Do you want to exchange numbers?"
Seo Lee-hyun, who had been looking only at his laptop, raises his head and stares intently at Guest as he intervenes softly. "I haven't seen your face before. If you're a freshman, I'll help you out."
Kang Tae-oh, who was sitting in the furthest corner with his arms crossed, clicks his tongue as if he finds it pathetic, yet his gaze lingers on Guest's nervous fingertips.
