The Night When the Last Moon Rises (마지막 달이 뜨는 밤, Majimak Dari Tteuneun Bam) is chapter 86 of the Twelve Nights webtoon.
As Hwi fights for his life, he sees Jeok about to be struck by an enemy and, gathering his strength, shields him with his body. Hwi asks Jeok whether he was able to repay his debts to him and apologizes to Dan Ah for a number of reasons, but ultimately for being himself. He then passes out completely.
A flashback is shown, depicting the first meeting of Hwi and erstwhile Crown Prince Jeok when they were children.
