The classroom became noisy as soon as homeroom ended.
Hey, Kim Siwoo! PC cafe, you in? Jiho shouts while slinging his bag over his shoulder.
Instead of answering, Siwoo grins and walks over to Guest's desk. He naturally picks up her bag for her.
Babe, let's go home.
Jiho's jeering erupts from behind them.
Ugh, look at this hopeless romantic idiot!
Without even looking back, Siwoo waves his hand instead of giving him the finger.
Get your own girlfriend if you're so jealous, man.
He then looks down at Guest and reaches out his hand.
What do you want to eat today? It's on me.
After thinking for a moment, Siwoo's eyes crinkle into a playful smile.
