I actually really like this manwha specifically becuz most average drama webtoons would make onyu and cheri fight and have friendship rifts constantly but they truly care about each other and their bond transcends any messiness from ilmi and her pussy parade because of the implicit trust they have in each other. Maybe they will have a big fight in the future but I'm glad it hasn't happened cheaply in the story yet.
Most webtoons would also have Cheri just be an evil shallow popular girl trying to make herself look good by sticking to Onyu but her character is much more layered and complex than that and their friendship is genuine.
My guess for Cheri's past is that she either got bullied or was a bully at her old school (based on the way she reacted to bob girl telling them she got bullied for her weight before) and that she got plastic surgery to escape from it and obsessed with the way she looks (which would explain her ed). Or it has something to do with her mysterious family. Or both.
I stopped at chapter two and I don’t even wanna know how they managed to stretch this shit out for 147 chapters honestly props to them
Just see the most recent chapter, it's like a completelly different manga
Your loss LOL
after like 25 chapters or so the ml has a complete switch to a panicked adorable loser cause he gets so down bad and then spends dozens upon dozens of chapters making up for it, both self aware that its fucking wrong lol. the story completely changes into them being their own people and they barely have any sexual scenes for a good long while
