Mirio is an affectionate and sunshine Boy always give you hugs 24/7
•Mirio Loves to give you Big bear hugs or tickle you if he's in a very good mood if you not much of a hugger or tickle person that's ok! High fives are just as amazing as well! He would never overstep a boundary.
•Mirio loves to make you happy it's his number 1 goal! he loves to make you smile, laugh, or anything that brings positive emotion, and if you ever feel sad this dude turns into a whole-ass mom he make sure your are comfortable enough to tell why are you feeling that way and if some caused you to feel that way let's just say they're just gonna get more then a punch in the stomach
•He knows it is wrong but he likes to use his quirk to go through your walls and watch you sleep only uses his face tho he thinks it's adorable to see you all curled up in your blanket dreaming he always wondered what your dreams are like if he notices you waking up then he'll quickly back off if you have a bad dream he'll.cone making up an excuse saying how he heard you struggling in your sleep and comfort you
•Every morning Mirio would invite you to walk you to class and when you get to your class he gives you a hive five or a big hug before he leaves
•On educational class visits he always yells out a hello or runs to you giving a big hug even ignoring how he embarrassed you in front of the class
• speaking of the class mirror Always sense how Jealous your classmates are whenever he wants to talk to you your classmate suddenly appears and pulls you away from him he didn't think much of it once he realizes that they were doing it on purpose (expect for izuku) and in the morning after before he was gonna give u a big hug iida got in the way and told you that aizawa is almost here and you should sit down (Aizawa was 5 mins late) mirio saw the pattern and smiled wickly walking to his group with a plan
"two can play that game~"
•Tamaki is the obsessive and Protective type of yandere Is shy and anxious on the outside but deep inside this dude is obsessing about every little thing you do!
•When Tamaki met you thought Mirio always talking about this Student all the time both Neijire and he looked at him curious about who is the student that made mirio that way and when mirio introduced you to them neijire instantly fell in love while Tamaki was shy as usually but there was something different about u a feeling that makes him think he needed to protect you he tried to surpass his feelings but how could he your so adorable and ur in class 1a the class that the villain target!? Poor boy almost made himself cry when the thought of you being helpless getting kidnapped
•Tamaki loves to steal little things you don't care about and keep them in his collection either be pens and pencils or items that you never use he'll collect them and put them in a secret place only he knows
•Tamaki would occasionally compliment you every chance he gets so he can see you beaming with happiness
whenever you're sad he's not exactly good at comforting people but he would give you comforting head pats or give you your favorite comforting items to calm you down and hug you if you need it but if someone caused you to be this way his whole mood turn he turns from an Anxious introvert to something even more threatening how dare someone hurt their baby sibling he was thinking the most horrible ways to torture the person who hurt you
•Since Tamaki is also friends and partners with Kirishima I would imagine Tamaki teaching Kiri to be more protective and be more supporting try to get the reader to date him he doesn't know much about love but he does know about protection and will try encouraging kiri and whenever kiri rambles about how amazing and manly you see he happily listens
