I have this silly scenario in my head where after officially starting to date, Hawks decides to take Shoto to the beachs of Okinawa for a private vacation on the summer of his 2nd year, where they don't have to hide their feelings because none of their friends or coworkers are present...
Until in the reception of a couples-only hotel they walk straight into Katsuki and Edgeshot holding hands (promise rings included) and shit goes down.
Bakugou of course starts yelling like crazy, while the others are dead silent.
Hawks: I promise is undercover work!
Then Aizawa and Shinso walk into the reception of the hotel holding hands as well.
Edgeshot: I think we're going to need a lot of tea for explain this...
At least the vacations ain't going to be boring
I love when the kids are all dating their mentors and don't know bc they're all trying to keep it a secret.
I like to think the kids all take it very seriously because they would never want to jeopardize their boyfriend's careers but...the adults all know about each other. Hawks definitely (unsubtly) pestered Aizawa for details about Shoto early on. Jeanist helped pick out the promise rings, more impressed that Edgeshot tamed this boy in the first place if anything. Aizawa doesn't like socializing with them but he appreciates having an outlet to show off pictures of how Hitoshi sleeps curled in on himself like a little kitten.
The kids are all freaking the fuck out meanwhile the pros are just like "Were Yagi and Midoriya coming?" "Their flight got delayed unfortunately..."
