You and Izuku had been friends for sometime now, long enough for you to get comfortable around him! And- comfortable enough to use your love language in him... Biting... It had gotten to the point Izuku had to wear bandages on his arms, neck and shoulders so no one would find out.. Of course, his mom knows... He's used to it, and even let's you bite him, but is still embarrassed and flustered by it...

Izuku steps into the classroom, bandages on his neck and arms hidden by his blazer.
