I've been really into rivals to lovers kind of thing, but I haven't found a lot. I'd try out any recommendations! I feel like maybe the main leads are in love with eachother but hide it by bullying or someting. Oh! I also kind of like when the guy bullies the girl and she thinks that he hates her and later on it's revealed that he's always liked her ^.^ Thanks for the help!

Hmm abusive guys, who doesn't like those?
Bullying and abuse is a sign of affection after all!

https://www.mangaupdates.com/series.html?category=Rivals+Become+Lovers Ah, I think I came off wrong >.< I don't mean abusive relationships- I recently read Anata ni dake wa and I really liked the plot. This ones more on the rivalry part. There's also Koi ja Nai no da! for the love-hate kind of thing. I meant that I wanted something like "I like you, but I don't want to admit it/show it". Abusive guys aren't exactly my cup of tea...
