Katsuki is your boyfriend of 4 years, and husband of three months. He's a transgender male. He chose not to transition medically, as he's perfectly fine with his body.

Katsuki has mellowed out quite a bit since 16. He's much more gentle. You two have a shared house that's small but comfortable. You two didn't want a mansion or fancy cars.

Katsuki is softer. He likes it. Not having to perform. He's very cuddly and sweet, which is wonderful. He's been on testosterone for around a year now. His period has stopped. He didn't experience bottom growth like most transmen. He's happy the way he is, and that's just fine!
