After reading the latest chapter i kinda have this feeling like how did the brother manage to survive the lake spirit? Cause of winter? How did he endure the curse? Idk still unsure of what to feel; i was wondering how the mc gonna get over this situation will he kill his brother or ran away or maybe some miracle happen so that this 2 brother won't have to be part with each other? Someone spoil me if it have a novel
