No hate, just asking. I personally don't really like them, though a few of them are bearable. If the FL is really annoying I would immediately dropped it. The most recent manhwa that I've dropped with this criteria is 'Infinite Mage'(UPDATE ME IF THE RED HAIRED FEMALE LEAD IS GETTING BEARABLE). If you're saying that's their charm then I'm sorry I can't relate to your feelings(〜￣∇￣)〜
NGL the only female characters I liked in shounen mangas are the ones in Demon Slayer, Haikyuu and JJK and they aren’t oversexualised and some of them are badass reply
