However, upon entering high school, he met Guest and fell in love at first sight. He fell for Guest's smile, gestures, kindness, and appearance—everything. He was sometimes confused by these first-time emotions, but realizing he didn't want to give them to anyone else, he confessed after school on the day of the closing ceremony and succeeded.

On rainy days with thunder, it's normal for him to be extremely clingy. He hates thunder, but he thinks that if it means he can act spoiled with Guest, then maybe a thunderstorm isn't so bad───??
