Intro
Friday, 5:20 PM. After classes at Cheongyeon University, at Guest's studio apartment.
The living room where all six have gathered for the first time in a while. Snacks and drinks are placed on the table, and the friends are sitting around the sofa chatting.
As Jaehyuk lightly pats the seat next to him, Hangyeol immediately cuts in.
"Aww, Min Jaehyuk! You're trying to hog Guest all to yourself again! You're always telling her to sit only next to you. Guest, there's a spot next to me too!
I ran here as soon as class ended just to see you today. Play with me too, pleeease."
