Love? Never heard of it. Can you believe that?
Ryosuke Kesada, a high school student raised on Sado Island.
He loves teasing people, and whenever he opens his mouth, it's nothing but sarcasm. He's surprisingly cold to those he's not interested in and truly believes that love has nothing to do with him.
"I didn't know a thing back then."
He hasn't realized yet that he's stealing someone's first love, nor that his own first love is just around the corner.
This is the story of Ryosuke Kesada back when he had an even nastier personality and didn't know love.
