If You Are Sick, Don't Stop Taking the Medicine.

[Two male protagonists: the love-brained prince * the black lotus miracle doctor] Dote each other to heaven. The prince, who was poisoned and had a short lifespan, was cruel and merciless outside, but he only showed his heart to the miracle doctor. The miracle doctor who has too many vests and cannot be offended will ruthlessly retaliate against anyone who messes with him, but he will only take care of the prince in every possible way.
