Bakugou has an abusive mother, anxiety, ptsd from being kidnapped,he thinks he's a loser and a lot more. And when he got his quirk and deku didn't he started to beat Deku up even tho they where childhood friends. When deku got into UA high bakugou thought deku was looking down on him so bakugou started to tell deku(midoriya) stuff like "I'm better than you nerd" "why are you even here your quirkless" and the one that got to deku the most was... "take a swan dive off the roof will you. Know one will miss you" and after all the pain and depression he had not to mention ptsd and anxiety. Deku couldn't take it anymore so he tried to jump off the roof but luckily shinsou was on the roof eating. See shinsou quirk is dubbed brainwashing, a powerful ability that puts those he commands verbally under his mental control. Which means he can ask people questions and if they are under his quirk they HAVE to tell the true. And if he gives a command the have to do as she/he/they are told.so when he saw deku on the roof about to jump he used his quirk to stop him."M-midoriya why would you do that?" "Why would you do that I wanted to jump I wanted to die!!!" "w-why would you want to die?" (Shinsou uses his quirk to see why deku wanted to jump) "why did you try to jump?" "Because know one cares about me, I'm useless, and I was put on this earth to spread my. legs" (shinsou stopped using his quirk blushed a little and hugged deku) "who told you this mido?" "K-kacchan" "THAT BASTARD WHY WOULD HE DO SUCH THINGS TO A CUTE LITTLE BOY LIKE YOU WHAT DID YOU EVER DO TO HIM" (mido kisses shinsou to shut him up) "your hurting my ears" (mido might not have a quirk but he is a neko) (the nekos in this story are momo,deku,todoroki,denki,and mina) "y-your ears?" Shinsou said concerned (deku popped out his tail and ears and sharp fang like teeth grow in his mouth) "I-I'm a n-neko" "so your a natural born bottom" shinsou smirked after he said his sentence "how about we go my dorm and play 20 questions after lunch to get to know each other better" "ok" deku said while smiling (this was the happiest he has felt since him and bakugou where actual friends) (shinsou blushed and grabs mido's hand and walk to the cafeteria) (since class 1-A didn't want deku being around them anymore shinsou brought deku over to class 1-B side of the cafeteria everyone in class 1-A was looking at deku and trying to get him to come back over to there side then todoroki got up and tried to drag mido to the other side) "midoriya come on you aren't supposed to be over here!" Todoroki said angrily "n-no" (todoroki starts to pull deku but the whole class of 1-B got up to defend him then shinsou spoke up) "listen here mido has tried to kill himself because of yall he thinks he's worthless, a waist of space, and a lot more. One thing y'all forgot to do it listen to him. He has ptsd,depression,anxiety,and not to mention sometimes he has panic attacks. Did any one of you know that?" (All of class 1-A looked down and shook there heads no) "you will see him in class and that's the only place you'll ever see him in. We'll be changing his dorm he will stay with me if any one of you try's to lay a finger on him god help my soul I'll kill you" Shinsou said with a sturn look in his face. "Come on mido" shinsou said in a soft tone of voice (mido got up and jumped up onto shinsou so he could be took to shinsou's dorm room) "I-I need t-to get m-my stuff out of t-todoroki's room" "I'll go with you I don't want you around him to long" (deku blushed then put out grabby hand so shinsou could pick him up shinsou picked him up)
