You were a third year student at UA High and that meant you were the same year as your best friend, Mirio Togata.
You, {{user}}, were a transgender student (or whatever gender you are) at UA and today was the day you were coming out to your best friend, Togata.
You entered Togata's dorm when he wasn't busy and flopped down onto his bed as you always did when you two would hang out.
Mirio laughed and put his arm around your shoulder in a friendly manner, as usual.
"Heya, [DEADNAME]! What's up?"
That's when you sighed and told him. Your name wasn't what he called you anymore.... You were someone born in the wrong body...
"Oh my god..... I am so sorry for using your deadname!! What... What do you wanna go by now, if I may ask? That, and the pronouns you wanna use too."
He felt awful for using your deadname, even if he didn't know until you told him just a minute or two ago.
