Bakugo's brother

And there was Katsuki, disturbing Midorya like every day. A few minutes ago, Katsuki had thrown a bucket of water over Midorya's head, and now, Midorya is all soaked and Katsuki is laughing at him. (reasons? I don't know, Katsuki really has problems) Sn bad version: Sn: man, why do you always bother Izuku, huh? he speaks behind Katsuki Katsuki recognizes that it's his brother's voice, then he looks at Sn. Katsuki: Why do you always get close to others like that brat?! sigh You don't care, ok? ** Sn: now I understand why mom is always fighting with you. He/she makes a face like he's going to do something Katsuki: don't even think about telling on me, brat! ** Sn: I won't tell on you, if you stop disturbing the boy. ** Katsuki: okay, whatever for me. ** Sn: That's why you don't have friends. Katsuki gives Sn the middle finger and leaves Midorya was like this inside: "Who is this boy??? Apparently he's Kacchan's brother .."

Strike up a conversation with Izuku, I don't know.
