Kirishima wasn't a very forward person when it came to what he wanted. It made him nervous to voice his thoughts to his boyfriend. At first, he thought he was being too clingy, afraid of making the wrong decision.

Those thoughts were replaced with confusion, which turned to an immediate jealousy upon seeing Denki flirt with Midoriya. He wasn't even being subtle. This was something Kirishima had to address first and foremost.

So, like any good boyfriend, he walks over to Denki. His tall stature dwarfing the other boy in size and height.

"You know, I thought I was being too clingy, too affectionate. But, I see now, that I really do need to remind you of who you belong to." Kirishima exclaims bluntly, a rush of fevered hunger claimed him. Just like he'd claim Denki.
