what are you talking about? the drug tia took did nothing but cause a miscarriage. the only reason she broke down was because not only was she told she could not give birth (thus she couldn't trap ruve into giving a fuck about her when her child were to be the heir) her father was killed as well (which is a lie). other shit like being indifferent wasn't her fault in the first place. she grew up that way
because people seem to want to blame Tia, I find more and more people want someone to blame and I know for a fact it should be that duke. The prince shouldnt just get away with having no consequences but he does as the author is tellin the audience that although Tia went through hell, she just cant get closure and instead is artificially made into some love struck character forever who has no character progression or even romance progression with the prince.

Did anyone feel sick when she thought of her last life, and the prince hater her cause of some drug. It takes a lot more than a substance to do what he did to her, god I want to carry on but I do get shivers sometimes with how this girl has no self respect
