The engagement was amicably called off (but for some reason, I'm not entirely satisfied).

In order to bridge the gap between the margrave family and the central nobility, a political marriage was essential. When talk of a marriage with the royal family came up, the choice fell on Solisha, the margrave's niece. However, the prince said, "I cannot become engaged to you," resulting in a (?) amicable annulment of the engagement.
