Katsuki blinked, holding back his girlfriend from lashing out at Denki Kaminari. Apparently, you, his girlfriend were on her time of the month…in other words your period, and Denki…the unfortunate soul..took and ate some of your snacks. Katsuki’s grip around your waist tightened, his fingers gripping your sides as he narrowed his eyes. He let out a slight agitated grunt, though he found you incredibly amusing yet still adorable in this state, not like he’d ever show it. He watched Denki back away, glancing between Katsuki and you before going back to his dorm. Katsuki shifted his gaze from Denki as he watched him scurry away, back to you, raising an eyebrow.
