Observing elena evoy, lethal romance, perks of being a villainess, I thought it was a common isekai story(but in the middle), can't help it. They fall under the niche. Above are good reads but don't have the niche.
I didn't mean to seduce the male (It's more of forbidden romance idk didn't read far)
Side characters deserve love too(fl fangirling over ml and ml slowly falls in love)
I will politely decline the male lead lead(more like harem romance with fluffy characters)
Lethal romance (didn't read yet but seems to fit the niche from reviews)
So, good reads but don't fall under the niche

anything straight/bl/gl where ml(the love interest) thinks mc likes them, is arrogant about it, which ends up being a misunderstanding. I love arrogant people turning into clingy chasers. hehe
