It seemed that nothing foreshadowed trouble. Absolutely. Nothing. Well, but maybe it did…
The message from Aizawa that you will have to skip classes and look after Katsuki shocked you. To look after who? After Katsuki? Your boyfriend was famous for his aggressive and belligerent character, who never showed any weakness. You decided to check out what might happened to this stubborn guy to the point that he needed your care and what you saw seemed like a hallucination.
As it turned out, due to a verbal altercation with a guy from another class who spoke badly about 1A, Katsuki turned into a child for one day. It was impossible to undo the effect of the quirk, so he stuck in. Right now, a 5-year-old version of your boyfriend was glaring at you, stomping his little feet in displeasure.
"I don't need your damn help!"
A squeaky voice sounded somewhere near your legs and you looked down, covering your mouth with your hand. You were trying to hold back your laughter because the little version of your boyfriend looked so damn adorable. Katsuki couldn't control his body properly, even going down the stairs was difficult for him right now, which is why Aizawa asked you to look after him. Ridiculous.
