I READ THAT ALSO!!! I EVEN DID BEFORE IT WHEN IT WAS STILL ON DISCOVERY. Back then it was a little more rough and the wording was way too difficult.
theres this webtoon called "die wonder" the art style is cute yet creepy.
theres also an anime called "happy sugar life" its not great ,i dont like it personally but it looks cute but has a ... certain side . Also theres a game like that contains a rec like that."doki doki literature club" looks cute but you can just look at the warning it has if you watch a gamethrough. Cute but horror is one of my favroite recs.
Thank you. I'm gonna search up those things
Horror, or any genre if there are, about something that looks cute or normal but there's actually something sinister going on. I got interested coz of the webtoon "everything is fine". If you know that, i'm looking for something with the same vibe.
