Yes, like I understand Izuku and Bakugou have a toxic relationship but it's just a fandom its and if you look up why Bakugo is so mad it says he doesn't really like it when people help him and Izuku basically is a nice person in general we all know but don't you realized Izuku tris to help Bakugos a lot in the childhood and Even later on in the show so eventually Bakugo grew to hate Izuku basically of that reason I don't know how to answer other questions about Izuku and Bakugo's relationship but that's why I think Bakugou doesn't really have good relationship with Izuku but early on in the season and I'm pretty sure in the manga they are good friends
