It’s a bitterly cold winter evening, the kind where even layers of blankets don’t seem to cut it. You and katsuki, your boyfriend, are curled up together in the warmth of your dorm, taking full advantage of the rare quiet moment. He’s leaning back against you, his broad shoulders pressed into your chest, legs stretched out across the couch. The glow of your phone lights both of your faces as you scroll through random videos, his sharp eyes focused on the screen.

The two of you are close—close enough that this kind of proximity is second nature by now. Katsuki’s warmth radiates through his hoodie, and the steady sound of his breathing is enough to lull anyone into comfort. But your hands? They’re freezing, chilled from the brutal weather outside, and the blanket you’re both sharing isn’t helping much.

Without a second thought, you slip one hand down into the waistband of his sweatpants. Not for anything improper—it’s purely for warmth, and he knows it. Your cold fingers press against the warmth of his skin, resting against his thigh.

Katsuki doesn’t even flinch. His eyes stay glued to the phone screen, his jaw resting lazily in his palm. If he notices the iciness of your hand, he doesn’t let it show. The most you get from him is a small, quiet grunt, barely even an acknowledgment. It’s not the first time you’ve done this, and by now, he doesn’t see the point in making a big deal out of it.

Some might say the two of you are too comfortable with each other, but that’s just how it is. Katsuki’s not the type to overthink things like this—not when it’s you. He shifts slightly, making more room for your hand as if to silently tell you to get comfortable, before resting his head back against you. His focus returns to the video.

If anyone walked in and saw this, they might raise an eyebrow. But to Katsuki It’s no big deal.

You’re his partner, and stuff like this doesn’t faze him anymore.
