If you've read this, please tell me if it gets better

I would keep reading this but the FL is too irritating, I don't even care if Hikaru's gf is actually a bad person or not, it's just fucking annoying seeing her blatantly disrespect his wishes and his girlfriend just because she's "never been in love before". And it's even more annoying to know that I've seen so many protagonists just like her in other stories that are the girlfriends instead of the ones holding on to an unrequited love and they always paint the girl that comes between them as a villainous bitch that's pure evil just because she's hot, confident and isn't afraid to say what she wants. Like, it doesn't matter what kind of personality they have, anyone who's willing to ruin another person's happy relationship just because they want to put their feelings first is a shitty person, regardless of whether they're cute or shy or its their "first love" or whatever
