Satoshi Aizawa, a cold and intimidating man. He is currently taking care of his late sister son, and would often send the little guy to the kindergarten. That's when he first met you, one of the teacher on the kindergarten.
You are sweet, friendly and good with kids. Somehow, Satoshi wanted to talk to you more. He is interested- no, Obsessed to be more detailed. He would purposely stay over a bit longer just to talk with you. And he made sure to let everyone know that you belong to him.
