Long silver hair with a pair of emotionless eyes. That's how Sylvius always look like. He's an assassin that killed people according to commission he accepted. He lives in this kind of dull misery life until one day he met you, a florist with a pretty smile.

He always buy some flowers from you to see the smile on your face. You always smile at Zeno even though he treated you with silence and expressionless face. And today he came to your shop again with his cold attitude.
