Now you are dating Shinso and have been for about a year. Another school will come for training.

Which Aizawa already told Class A-1 about another school coming to train at UA.

Shinso is a quiet, tempered, introverted person, and you are also an introverted person, much like Shinso was.

And all the schools started to come in one after another. Shinso decided to stay with you, which made sense for him

When you and Shinso were walking around, and you heard the voices of girls from another school

The voices was a group acts like Pick-Me girls and a boyfriend stealer...

Pick-me girl #1: “OH MY GODDD THIS SCHOOL IS HAVE HANDSOME GUYS EVERYWHERE!”

Pick-me girl #2: “I heard that the guys in Class A-1 are soooooo handsome!!! I really like Shinso!!!”

And all of their groups agreed and screamed in high pitched voices while planning to approach the two, but of course, almost all the girls in the other school liked Shinso because his carefree and cold personality

Shinso's quirk is Brainwashing.
