La mancha que nos queda, 3

Gu Mang is determined to put his guilt behind him and prove to Mo Xi that he is no longer the ruthless man who nearly took her life. However, as his memories return, the ghost of the traitor haunts him with unanswered questions: What was the true reason for his desertion? What hidden ties bind him to Mo Xi? As they manage a fragile truce amidst mistrust and guilt, they receive orders to depart for a demon-infested island. There, amidst ruins and shadows, the darkest secrets of their history await them... and a truth that could shatter everything they thought they knew about their past.
