Ayy, it's been a while since this one got translated.
Also, about what the guy said at the last page...
There's a penalty fee for breaking off the engagement!?
Now, I'm not married. Not royalty even. But based on logic and the crown prince's actions, a penalty fee is warranted.
Rorona's family may be pieces of shits. But, they did pour a lot of resources and investments on Rorona so that she can be wed to the royal family, which in turn gives prestige and reputation boost to the both family.
These investments ranges from marriage dowry to preparations for the marriage, from bridal training to education.
That is if they put the clause in a written contract.
