Lately, you've noticed how.. nice, Katsuki had been getting.

One time, you jokingly ordered him to buy you a drink, and he suddenly did without any pay in return. Or like the other time when you couldn't open a lid, he suddenly came out of nowhere and opened it without any hesitation, giving it to you afterwards.

But anyways, right now you were styling your hair, you didn't liked every attempts to make the hair strands out more, but you kept trying. Until... "That's not how you do it."
