So, main character licked her phone while looking at a picture of her friend. Then, she actually kissed said friend while she was asleep. After that, MC had fantasies about... sexually assaulting her? Paraphrasing, but, "if she's going to hate me either way, I might as well just do it", followed by her having a fantasy about stripping and groping her childhood friend.
Maybe I'm just innocent and naïve, but all of those things sound way beyond normal, and just quickly got worse and worse. Ended up with a happy ending, but MC just seems downright creepy to me.
