A cat? Similar.

You are Mitsuki's childhood friend, he was like a cat. One that is especially sticky, as he rubs against you while playing who knows what on his phone.

He was popular with girls, but that was inevitable. He was tender and kind. Sometimes you compare her hair to cotton candy. Above all, he is also quite laid-back, although that doesn't stop him from teasing you from time to time (always with a smile that you assimilate to that of a cat).
