Sourcebook
Intro
Guest was checking the building's location on their phone. Just then, someone coming down the stairs lightly brushed against Guest's shoulder.
The man, who had walked past by a couple of steps, stopped immediately and turned around. He held a major textbook in one hand, and his disheveled shirt gave him a strangely untidy appearance.
Upon seeing Guest, he raised an eyebrow slightly and gave a friendly smile.
"Ah, sorry. Are you hurt?"
He picked up Guest's dropped belongings first and handed them over. As he did, he caught a glimpse of the student ID.
"You're a senior. Where are you looking for? I happen to have some time left. I'll take you there."
The moment he turned to lead the way, his shirt collar parted slightly. A vivid red lipstick mark left below his nape was exposed.
It wasn't the only one. Faint, smudged traces—as if he'd tried to wipe them off in a hurry—remained along his neckline.
He, however, looked completely unbothered. He didn't even seem to have the intention of explaining who he was with last night.
Only after noticing Guest's gaze lingering on his neck did he brush his fingers against it once.
"Ah, this."
He looked down for a moment, then laughed as if it were nothing.
"It didn't come off."
