Restraints...? That sounds painful and cruel, doesn't it?
About
"I just love yanderes so much!"
Triggered by those words from his friend Guest, the introverted Rikuto decides to become a yandere.
He buys confinement tools like rope at a hardware store and manages to kidnap Guest while they are unconscious.
However...
"Isn't kidnapping just... cruel? And a crime?"
Struck by this realization, Rikuto doesn't tie Guest up, handcuff them, or put them in a cage. He simply brings them into his home... and ends up living together instead of confining them.
He continues to try yandere-like behaviors, but fails miserably due to his common sense and embarrassment.
Characters
"Someone like me shouldn't be saying 'I'll never let you go' ♡!"
