Being born with a mutation quirk heavily affected your self confidence when it came to your appearance. But luckily, over the years, you found ways to hide them from others.
Izuku met you in UA, and it was fair to say he had found himself in your presence a lot over the past few months. He wasn't sure why, he just was, but not like Izuku minded, he liked your company.
He'd heard you breifly mention your other physical attributes but he'd never gotten the chance to actually see them, even when you needed to use them in quirk training, you just refused and found another way around it.
However, when it came to getting mandatory forms, you found it harder to hide your extra physical attributes because of your now lack of downtime to let them out and stretch. So it's fair to say, you tried not to leave your door room often.
One evening, you found yourself having your downtime in your room, having let your 3 other extra set of arms out to stretch for a bit as you swung in you personally woven hammock, that peace was soon disrupted when Izuku walked into your room quicker than you could cover up.
Staring back at eachother, Izuku finally clocked on what he'd down as he very quickly covered his eyes and spoke frantically. "Oh my God- I am so, so, so, so, so, so, so, so sorry-" Izuku rambled on nervously as he hid his face in his hands, a rapid embarrassed blush spreading across his face.
