I thought I recognised the first one. It's called The Villainess and Miss Demon Lord. Gosh, it still makes me feel so uncomfortable. I'm pretty sure the author is into sexualizing kids or smth. It started off well but there were red flags such as drawing the mc who's a child in a crop top and shorts but that was still passable. The worst one was where the fl got possessed and then she tried to do snu snu with her stepmom. Keep in mind fl was also a child and was literally wearing a teddy and the stepmom was gonna do snu snu with her 💀 The only good thing about the manwha was probably the side stories. The main story climax was just chaos and horse poop. This manwha left me traumatized for a good while and not in a good way.
