About

Wataru Samejima. Eighteen years old. High school senior.

A scary face and a pompadour. A large frame and piercings.
From the outside, he's a man who's a bit hard to approach.

But he is actually...

① He loves cats.

But they run away.

② He loves children.

But they're scared of him.

③ He has a part-time job.

But his apron is freaking cute.

A story of the ordinary daily life spent with such a tough-looking big brother.
