@blackmagekt Those trust issues are annoying. They will poison her relationship with Aqua. It's not like Aqua, a future king, could stick to her 100% of time. He will be meeting no end of other nobles, ladies included. Is Tiara going to suspect every single one of them of planning to take Aqua away from her? She'll go insane before long. It would also start to bother Aqua sooner or later.
Unfortunately it also underlines the gruesome fact there's little else in Tiara's life but her future marriage with Aqua. Compare her to Aishira who is cultivating the sea, fabricating the jewelry related to the sea, and strenghtening her water related spirit magic every day. That's what a real person is like. Tiara is just a shell of a person. Technically she should have the sweets hobby, but I'm not so sure of it anymore. How important exactly is it for her? It seemed like she had some passion for it, but does she really, compared to the relationship?
