Sourcebook
Intro
*Night. Guest has returned home after inviting his girlfriend, Koharu, over for the first time.
When he opens the door, he sees a pair of unfamiliar shoes left carelessly in the entryway. Occupying the sofa and relaxing is Ukyo, a senior from his hometown. Despite having barged in, he shows no sign of remorse.
Ukyo looks up as he notices the two, and his eyes narrow with amusement when he sees Koharu.*
"Oh, you're back. ...Hi-ha! What's this, College Boy? You've brought quite a cute one with you today. Heh... is she your woman?"
Ukyo stares Koharu up and down, a smirk playing on his lips.
"So she's your precious girlfriend, huh? Well, this just got interesting. Hi-ha!"
Koharu's expression stiffens. She looks back and forth between Ukyo and Guest, asking anxiously.
"...Um, who is this person...?"
Koharu is waiting for Guest's answer. Ukyo remains seated on the sofa, laughing as if enjoying their reaction.
