The bakusquad loves to communicate through memes and vines randomly, like Bakugou being Bakugou will yell at Denki or someone and then kirishima will just look over and go "Adam," and Bakugou will turn to kirishima to yell but then break down laughing which he only does alone around the squad. Or someone will lose badly in sparring and get knocked out and Mina will just quietly say "oh ma fuckin god she fuckin dead." Or to greet each other from a long ways away, Denki will just walk into 1a and yell "HOW DO YOU KNOW WHAT'S GOOD FOR ME" and mina or sero will finish it.

Mitsuki used to have a massive collection of big plants, and Midoriya used to come over when he couldn't be outside like if it was storming. He and Bakugou would spend hours playing around near the plants and pretending to have jungle adventures, or playing hide and seek, Mitsuki even made a 'game' to see how many plants they could water and whoever got the most would get a little extra desert assuming Midoriya stayed that long. Midoriya still likes to decorate his room with tiny tropical looking plants to remind him of those times when he's feeling super nostalgic and missing the close friendship they had. He even takes a few of his allmight figures down to make room for the plants on his shelves.

When he's really upset one of his coping mechanisms besides training is spontaneously buying four or five new plants to calm himself down. If he's running out of room on his shelves, he goes over to todoroki's dorm and takes care of the plants he's given him from the few times Midoriya has gone over-board on his plant shopping. Todoroki has no idea why being around plants calms the freckled boy so much but he does know that he wants to help Midoriya with whatever is bothering him, and if the way to do that is to vent next to house plants with tea, then so be it.

Satou has a webpage where he has multiple tutorials for cooking and baking as well as at least 50 recipes. He decided before that if the whole hero thing were to backfire entirely he would open a bakery.

Todoroki is the kind of person that likes to save people under weird names in his phone, like Midoriya who is saved as 'Allmight's secret love child', or Uraraka who is saved as 'You'llFloatToo🎈' and of course there's Bakugou who is saved as 'Baku-bitch💣'

Bakugou, even though he hates most people, Midoriya imparticular, with a passion, he cares aggressively for 1-A. Like he'll notice one of the girls getting super bad period cramps and go out and buy comfort foods, some pain killers, and a heating pad and tell them to "FEEL FUCKING BETTER" or Uraraka will have thrown up from overuse of her quirk and bakugou will just pull a granola bar out of nowhere and toss it at her yelling "KEEP YOUR LUNCH WHERE IT'S SUPPOSED TO BE" or even if on a weekend after everyone has had a shitty week he'll spend most the early morning bitching about 1-A while making them all breakfast. He even cares aggressively for the teachers, like when Allmight coughs up blood he'll shove some tissue at him and growl "don't leave blood everywere" or Aizawa will have had a particularly small amount of sleep to where he can't barley teach without starting to nod off so while he's half slumped over fighting his fatigue bakugou will stand up and slam some 5 hour energy on his desk and say "get more sleep" he once even made recovery girl a thank you basket with a bunch of snacks and shit in it when he'd over heard her muttering about people never even listening to her saftey warnings in return for her healing powers. Though she was clearly just irritated and didn't really mean it part of him was compelled to do that anyway because it felt particularly aimed at Midoriya and his bone breaking habits.

(Sensitive topics)
Iida and Midoriya make it a top priority to make sure everyone has had any pills or anything they need to take and is in the best mental state they can be in, especially after Midoriya noticed faded scars on someone's wrists and made sure they got proper counciling for what caused it.

(End of sensitivity)
All of class 1-A goes full out for any teacher's birthday to make sure they have the time of their lives for that day
