MUSE B is a prince/princess. They are soon to be crowned as the king/queen, and as such, needs to be married. For the sake of the kingdom, MUSE B is being forced to marry the cruel prince/princess from afar, for the sake of a truce.
MUSE A and MUSE B are madly in love with each other. Sadly, this love is forbidden. It doesn’t stop them from seeing each other whenever possible, sneaking out behind the stables or meeting up in MUSE B’s bedroom after curfew. Things seem to be going alright for the duo. That is, until they get caught. Being seen as a traitor trying to ruin their contract, the king and queen sentence MUSE A to death.
