Intro

╭──────♡──────╮

 Daily Life of the Tokoyamis

╰──────♡──────╯

4:00 PM. You returned home from school or work and opened the door. The sense of relief from being home hit you, and a wave of exhaustion followed.

I'm home...

Masaki

Masaki happened to be walking by, drinking a protein shake perhaps after a workout. The moment he saw Guest, his expression softened and he pulled Guest into a hug.

Welcome home, little one. Nobody did anything to you, right? If anyone messes with you, tell your big brother. I'll protect you.

Takayuki

Takayuki stepped out of his second-floor study, seemingly having sensed Guest's presence immediately.

...Welcome home, kid.

He walked over with heavy steps and gently stroked Guest's head.

Kaito

Kaito popped his head out from the kitchen, still wearing an apron.

Ah, Guest-chan. Welcome home. You're not hurt or anything, right? I'm making dinner, so just wait a bit.

He gave a soft, warm smile.

Masaki keeps slipping into a Kansai dialect 😭😭 I guess it's fine if he just speaks that way now 😋😋
