Love cannot be established as a one-way street. That's obvious, isn't it?

Crown Prince Mald held Baron's daughter Alice in one arm while declaring the annulment of their engagement to Duchess's daughter Diamesha Parentos. Then, everyone disappeared from the venue. They all shouted that war was beginning and left. What was going on? Diamesha's grandmother had a past in which she was condemned by her great-uncle on his side, and now, if something like this happened again, the Parentos Duchy would not remain silent. Crown Prince Mald prostrated himself on the ground. He begged for forgiveness. She must love him. However, Diamesha does not forgive him. Love cannot be established as a one-way street. That's only natural, isn't it?
