The prince

Unpopular af opinion, but i don't think the prince deserves the hate he's getting? Not the current prince anyways. Past prince was scum. It's not the same prince though. She said herself that the prince used to treat her like he does now, not as bad as he does in the future, but something eventually happens that makes him hate her. There has been a lot of foreshadowing that he ended up hating her in the last timeline because of what she'd said about her mother when asked about her. The things that are happening in this timeline are changing his misconceptions about her, he'd thought she was deceitful like the rest of the nobles around him till he recently remembered how both her mother and Tia had never been like that even since they were both kids. He only remembered this because her actions in this timeline differed. In the last timeline she never had any friends, she wasn't on good terms with her father and she didn't seem to care about her mother. Over the course of years all the prince saw was her straight face as she did her duties, he never saw emotion from her like he has now. His impression of her became that she's a cold, heartless woman only focusing on being a royal. He still had this misunderstanding in the last timeline, it's why he didn't believe she had any good intentions in anything she did at the time that all that shit went down. He thought she wanted to be empress and cared about nothing else. During this time, Tia was learning about him to get him to look her way, doing small things for him, but because he had those preconceptions he took this as brown nosing, remember how he asked why she was doing all this before having sex with her to supposedly give her what she wants? He thought she was just brown nosing, he didn't realize her feelings, she never told him and even if she had it was too late by then. She took the opportunity to sleep with him as another effort to make him look her way, but this only "confirmed" his suspicions even more. In this timeline he's seen her many expressions with the people she cares about, this is a complete 180 on the impression he had in the past. It's like, 95% of what made him hate her is gone, now all that's left is the baggage surrounding Jeremia and the two of them. Honestly, it's been pretty explicitly shown that Tia just views Allen and Sein as friends, she still loves the prince (she all but says this while worrying that she's going to follow the same path as her last life on accident, devoting her life to him), she's just terrified of him because of the trauma from her past life. Once the baggage between them is resolved, I'd like for them to be together because it's what SHE wants and i feel like she's been through enough that she deserves whatever she wants. If things change and she actually falls for one of the other two, fine, though Allen is a creep (a sweet creep to her) as long as he treats her right it's whatever. ╮(￣▽￣)╭
