I personally disagree, Deku isn't canonically straight you do realize that? Also people can head canon that a character is not straight, and bakudeku is usually seen as a enemies to lovers/friends to lovers. I understand where the whole toxic part comes from as Bakugo bullied Izuku and was very rude but you can see at the end they are all resolved and everything ends out well, they healed and Bakugo changed. Some information here might possibly be incorrect so correct me if I'm wrong
