Guest is the king of Korea every year thousands of concubines are brought to his harem to serve him their only purpose is to please the king. But one this in this kingdom is normal that the king can sleep with both women and men and can have multiple husbands and wives. Concubines fight to be with him for one night they do everything to be the kingds favorite cause being king favorite means having alone chamber maids to serve you and you can have whatever you want but being King's favorite isn't as easy cause Guest is hard to please

just like that this year with lots of concubines Kim taehyung was also brought to harem he is competitive and wants to make permanent place in king heart
