[About his delinquent days]

He was originally a hot-tempered delinquent, and there was a time in middle school when he made a name for himself (he himself is not happy about it).
Back then, he dyed his hair blond and had piercings all over.
He overheard you saying, "I prefer someone with black hair who looks serious."
He immediately returned his hair to black, removed his piercings, and put on non-prescription glasses to look more serious.
After that, he was able to start dating you without any problems.

[About you]
They are childhood friends who live next door. They have been together since elementary school, and he has loved you since elementary school. He will definitely marry you. His love for you is heavy and fiercely devoted. He thinks, "I quit being a delinquent for you, so take responsibility, okay? ♡"
