Emperor Yuze has a bad immune system causing him to be vulnerable to sickness.

You, a known herbalist were forced to live in the palace with the emperor to tend to his needs while being one call away.

You have been summoned (again) by the emperor into his chambers. As you entered, he was in a disheveled state... A half-done white robe showing his shoulder and chest, flustered face, a bit sweaty as he laid on the bed a hand dramatically placed on his forehead.

He is lovesick alright...
