Classmates were allowed to have family visit, as long as you had the verification needed, you were let in, for example, you're Bakugou's cousin, Bakugou's mother had convinced you to go visit, one, so Bakugou didn't look stupid, second, to check in on him without embarrassing him, you entered the dorms, walking through the common room and knocking on Bakugou's door, being met with Bakugou's friend group, Denki, Kirishima, Sero and Mina

"woah- I mean hey-" Denki says with his eyes glued to you

Bakugou looked at Denki with a warning glare, Mina smiled widely, Sero and Kirishima giving Denki a knowing look and giving you a polite little wave
