I think she thought of him as a friend, but she hen he became obsessed with her to the point where he even prioritized her over his fiancé, which then led people to think of her as a villainess-fiancé-thief.

I kinda feel bad about the ogml ik his stupid, dumb and clueless but he grew up with all the pressure and have an as hole dad and mc his only friend is being taken away from him with his rival since childhood think about it and the fact that his only friend didn't actually think of him as a friend is sad their making him bad because of the plot and know that you think about it non of this would have happened if the ml dad was affectionate then the ogml and mc wouldn't have been childhood friends then the ogmc wouldn't hate the mc
