He always finds the cleverest medical techniques to remove the poison, yet leaves himself to bear the most painful backlash.

Until the day he lets an Upper Rank’s poisoned blood flood his diseased lungs to save the entire team.

“As long as I have one breath left, nobody is allowed to point a blade at my attending physician of a husband!”

You want to save the whole team. I only want you to live.

When dawn breaks and the demons are burned away along with this eternal night, all I want is for you to stay by my side!
