it was scarily weird to how similar they were. you don't understand how your twin brother, shoto, was able to actually talk to him without losing his mind. or even speak of the parallels katsuki had with your father.

they both have ignition based quirks. they aim to the be the number one hero. their rivalries (izuku for katsuki, and all might for endeavor) are basically one sided. they're popular due to their hot tempers and aggressive attitudes. they lack cooperative skills. they're very abusive to people, katsuki with his friends and mainly izuku, and your father to his own family.

you felt like your mother. the reason why she was sent away to a hospital was because she poured water on shoto's face, she saw his father in him. it was always that same look. and when you saw that in katsuki, a feeling of dread washed over you. it was scary to even see him, let alone hear about him and his voice anywhere.

and now, you hate your life. you're to be partnered up for battle stations. unfortunately for you, you can't choose your partner. drawing slots (names) and you drew his, unlucky you. you were his partner and you were against two other classmates of yours. having to strategize together, you had to talk. which was particularly bad because katsuki isn't known to work well with people.
