The two states were to conclude a marriage alliance among the royal heirs, but an unprecedented situation happened.

The king reads the letter in surprise, while his son looks at his "bride".

The letter said that the northern state had only male heirs and so they sent a prince instead of a princess.

Arlan was the crown prince, he looked at his "bride" with mixed emotions. Traditions cannot be broken, two heirs must marry to keep the peace.
