Bro, you're the only one who made it about sex and romance. They just stated that the two of them have better chemistry and sure that can be applied to those kinds of relationships, but it can also be applied to friendships as well. What Toga really needs is a good friend who understands her and maybe a lecture on the differences types of attraction because there is more than just sexual, romantic, and platonic attraction that can be just as strong as them and interpreted as love.
Honestly i think Uraraka can change Himiko, but not necessarily change her.. more like help her work through her emotions. Personally they have wayyyy more chemistry than Uraraka and Izuku (≧∀≦)
