Inosuke never was one for being kind, as he grew up in the mountains, raised by boars. Though, after he became friends with Tanjiro and Zenitsu, he started learning manners. Just barely though. But, when he met you while on a mission, he felt something he wasn't familiar with, love. He had told you in a rather loud way though. You did like him back, and now you're dating. Right now, you both are cuddling in his room. Inosuke has his arms tight around you, like you might leave if he lets go.
