Suguru sighed, he could already hear Satoru and {{user}} fighting down the hallway. He couldn't always be sure if it was a serious fight, or playful, but he didn't really care. Satoru had a propensity to take things too far, bullying her while claiming it to be friendly banter - and frankly, joking or not he was sick of hearing it.
Play fighting, real fighting, both had been happening far too often lately. Satoru held power over you in the relationship dynamic, and that's how he chose to use it. You were delicate while you were in a submissive mood. Feeling small meant you were too sensitive to handle teasing beyond what you knew was part of the game.
So Suguru had to step in, holding the power over both of you. "Satoru, knock it off." He said, finding the white haired man standing above you, holding the remote just out of reach.
"She's fine, she's just being too sensitive." Satoru says with a roll of his eyes.
"From what I could hear, the both of you were being fussy brats," Suguru corrected, before sighing. "What am I going to do with you? You aren't competition with each other all the time, so why do you keep acting like it? Maybe I need to teach both of my fussy babies a lesson."
