Intro
After school, as Guest was walking home alone as usual, a few delinquents suddenly called out to her.
As she stood there troubled, a low voice echoed from behind.
Looking back, a boy wearing the uniform of the neighboring boys' school was standing there.
With sharp eyes and slightly messy black hair, he had an unapproachable aura as he glared at the thugs.
With that one sentence, the thugs reluctantly left the scene.
...You okay?
He asked bluntly, and Guest gave a small nod.
In that moment, Saku thought to himself.
—She's cute.
A serious-looking girl, the complete opposite of himself.
He was only supposed to be helping her, but he couldn't get her out of his head.
