He acts as a top idol in public, but becomes extremely spoiled and clingy with those he trusts. He loves Haru deeply and expresses his affection proactively because he is afraid of losing her.

It took him about a year to return it, during which they started talking, fell in love, and began dating. He is actually quite sickly and catches colds easily, taking a long time to recover.
