On lez.. is called Spiteful Affection, I don't know if it has another title here, the premise is:
Best friends, household pet, or just charity case? Hayoon has no idea what she is to Minju after all these years. She’s grateful Minju’s family took her in despite her being nothing but a lowly recessive omega, but her relationship with Minju sure is confusing. Minju does seem to like her, whispering sweet nothings in her ear and helping her out when she’s in her heat, but who can tell? Ever the stereotypical rich alpha, Hayoon knows for a fact that Minju gets bored easily, that she loses all interest once she gets what she wants. Unable to tear herself away from Minju’s grip, Hayoon unwillingly comes to harbor affection, albeit spiteful affection, for her friend…

after Dreadful Night this is such a meh story is annoying and a drag finishing it. the concept is interesting, but the story and the characters are just bad. the plot could be done in 20 chapters or less it was just extended with nonsense and sex that wasn't even spicy, it was boring and I started scrolling past it. 43 chapters read so far, but it feels like 100
the author had some nice ideas, but wasn't able to properly expose none of them so the way the characters act lacks foundation
