I should have stopped at the lake scene and started marinating it again.
Anyway, spoiler for ramona—
Ramona who was the "original lover" isn't a bad person. She was jealous of Tia but never act upon it. In the end she even got motivated by being around Tia and wanted to take over the Brown family after seeing Tia, as a female, can take over the Lombardi family. Her previous goal was to become a knight for the imperial family, but it changed to becoming the head of the Brown family in order to also help side with the Lombardi.
