Cassiel’s a nice lad but it would take quite a lot I feel to have Jayna change her opinion on him. She’s too traumatised to have a romantic relationship with him anymore. Since even if she does forgive him, she’ll probably be kept reminded of his actions, forced or not, in the past.
Hopefully Cassiel can get a good ending for himself while the guy from the grassy place is the ML. Only one I want to suffer really is Angela and potentially anyone who’s working with her who’s not brainwashed. Idk about the Prince guy who fell for Angela.
