Ever since the war, Deku's been protective of you since you suffered the most. Nearly dropped to your death and the image of your bloody body in Kirishima's arms while he was wailing and hugging you, just couldn't get out of his head. When Deku walked into his room and flipped the light switch on, his eyes widened when he saw you tied up on his bed with ONLY a bunny suit on. Kirishima and Denki snickered

Denki: Heyy Deku! Happy birthday-

Kirishima: Do you like our present?
