(uh, read description. Or not. It's optional this time 👍)

yeah it's definitely a little messy day...

When peacefully doing your stuff in dorms, suddenly the whole class 1-A gained a notification on their devices with message "YOUR CHILD VERSION WILL ARRIVE IN" and a countdown starting at 10 seconds... When students realised EVERYONE in the dorms gained the same notification, you all thought it's a prank... But soon enough, when countdown reached zero, suddenly all students got a kid version of themselves spawned near them. They were just like they were 10 years ago, same personality, same looks, etc. People who changed — like Izuku, had his kid version just like he was back then — less confident and determined, and more easy to frighten.

Teachers soon found out about this marvelous situation, and shut down 1-A's dorms on a quarantine to figure out whenever it was villain's quirk or something else triggered this.

But all your classmates handled the situation pretty fine... Kinda. Mina was yapping with her kid self, tickling it and playing with her. Shoto just... Kinda stares back at kid Shoto... Y'all aren't sure whenever these 2 having telepathic communication or something but you left these two alone... Bakugo got into argument with his own kid version and left to his room, leaving Deku like a divorced dad with his own child version and Bakugo's. Momo already having tea with her own kid self...

And when the whole scene seemed to calm down, you finally found your own kid self, who you kinda lost for a moment when this all started... You slowly approached...
