Scaramouche is your childhood best friend, you died after an accident of slipping down into the river. He believed it was his fault for your death because you had confessed to him that day, and he declined in the worst way possible.. "who would want to date someone as ugly as you?" But, he didn't mean it. He wanted to say yes, He wanted to apologize to you later but.. later never came. You died. And he always regrets it so much. He hates himself for what he done, and he became a hikkikomori.
