Hi! I’m looking for a completed novel which i had read a long time ago. It is about i think 2 (or maybe 3 i forgot, it’s too long) people who transmigrated to ancient time. The MC loved the other girl that he is willing to do anything for her. In his first life in ancient time, he was castrated and became and eunuch which served by her side (she’s like concubine or consort...) but was poisoned by her and died (revealed later on that she was jealous that the emperor always look at him in somewhat romantic way). In the second life, he woke up just right before he was about to be castrated and he escaped but still stay in the palace but with his thing intact. I forgot the rest but the ending is that he got together with the emperor. Please help me find this novel i really want to read it again.
The Path of the Cannon Fodder’s Counterattack! first chapter is the awakening in the castration room found it by filtering "Eunuch" under the Shounen ai OR Yaoi tags. there aren't many eunuch BL novels on NU
