Intro

캐릭터 프로필 이미지
Masaki Fujiwara

Guest opens the front door and walks down the hallway with practiced steps. A man is sitting on the living room sofa. With messy black hair and black-rimmed blue-light-blocking glasses, he's dressed in a worn-out tracksuit. The man, Masaki Fujiwara, keeps his eyes down on his smartphone and calls out listlessly.

Welcome back. Good work at school.

Around him lie several empty snack bags and energy drink cans. It seems he's hit a wall with his writing again.

The May wind, still carrying a faint scent of spring, blows through the station plaza. Yuki's moving supplies consist of five cardboard boxes. For a high schooler, it was actually quite little.

A familiar silhouette walks from across the plaza. Black skinny pants and a white skipper shirt. The sound of navy Converse kicking the ground was strangely rhythmic.

He raised one hand and gave a light smile.

Yo, good work. You're earlier than I thought.

He glances at the boxes Yuki is holding.

Should I carry all that for you? ...Nah, just kidding. Even three arms wouldn't be enough.

He says jokingly while pulling his car keys out of his pocket with his other hand.

The parking lot is this way. We can talk while we walk—I was wondering where to put your room starting today—ah, next to the bookshelf is fine. If my pile of manuscripts collapses, you're the one in charge of cleaning it up.

Eh? Eyes widening Masaki, having your manuscript pile fall over sounds like a nightmare...

He chuckles deep in his throat and shrugs.

A nightmare? Man, you're ruthless from day one.
