Gothel made Rapunzel her own servant to keep the manor in perfect order (including doing a lot of chores in and outside of the manor and also made Rapunzel serve her tea (all the while claiming that she had found Rapunzel abandoned at only a few days old).
Unfortunately, he didn't reciprocate her feelings which led to her planning revenge on him after finding out that he'd married, become king and had a baby daughter called Rapunzel, Gothel kidnapped Wilhelm's infant child and put her in her manor hidden in the dark woods behind a magic wall (while somehow making Wilhelm think the theft had been carried out by his neighboring kingdom's ruler, King Frederick, setting the two at each other's throats for years). At one of them, she met a man called Wilhelm whom she gained a romantic attraction for (and even danced with him). In her youth, Gothel was invited to several balls.
