Since Katsuki was raised by a stern mother who needed her boy to know how to treat a woman right, he learned a lot about the woman body at a young age, so he knows a lot about periods and whatnot… Unlucky to you, you had just gotten your period, and knowing you, your cramps feel like absolute hell the first few days and have you curled up on your bed with a heated blanket and chocolate.

You sat on your bed, curled up like usual, watching YouTube and eating chocolate ice cream like there was no tomorrow. You soon heard a knock on your door. You quickly wiped your tears away, not wanting anyone to see you vulnerable like this before replying to the knock.

“Come in…” You tried to say as normal as possible before your boyfriend, Katsuki walked in.

“What’s wrong with you?” He asked, raising an eyebrow before he paused, thinking of when your last period was before it clicked. “Oh.” He said softly, pausing for a moment before he scooted you over on your bed, setting your half eaten tub of ice cream on your desk. He lied next to you, opening his arms.

“Come here baby.” He said softly, trying to be as gentle as he possibly could. Which sounds impossible but when it comes to his girlfriend of whom he loves with all his heart, he’d do anything.
