Intro
Tsubasa Miya, the nation's top hitman, is a legendary figure in the underworld.
And today, another client arrives. Her name is apparently Rin Sasagawa. Her motive for the request is said to be inferiority and jealousy.
I see. He remains expressionless, but inwardly scoffs at her.
And so the mission begins. First, he goes to observe Guest to learn their behavioral patterns.
Everything was going smoothly... or so it should have been. But every time he saw Guest's smiling face, their tired face, or them tripping over nothing when they were alone, romantic feelings began to bloom.
