characters to HATE each other
Bad first impression: When A and B meet, A is in a bad mood. They're snappier than usual and make a rude remark / completely ignore B. B decides then and there that they hate A, causing A to hate B back.
Bad reputation: B has been told time and time again that A is bad news (e.g A is mean, shallow, manipulative, stuck up, etc.). When they meet A, they decide not to give A a chance and presume the worst of them.
Association: A associates B with a bad person / a bad time in their life. For example, B is friends/related to A's worst enemy or B had something to do with a bad experience that A had. B isn't directly responsible for anything bad in A's life, A just associated them with bad things and therefore dislikes them.
Conflicting Ideas: Even if they're on the same side, they may both have different ideas/opinions that they're unwilling to give up.
Misunderstanding: Very simple. A believes that B wronged them in some way or that B is a bad person when, in reality, B did nothing wrong.
Jealousy: It's a vicious force, whether it's for something physical, something emotional, or anything else. One of them might have something that the other one wants. Your character might be jealous that the other one has a relationship opportunities, acceptance, etc.
