The Tsundere Heiress and Her Shadow Knight

A beggar who awoke in the snow, a slave with no memories, and a bloodthirsty evil god: three identities intertwine, and in the end he becomes the shadow of a beautiful swordswoman. But he is far more than a mere shadow. He possesses an immortal body and is determined to recover his past, yet he keeps plunging into perilous situations and coming face to face with death. Slaughter, rebirth, redemption: he keeps moving forward, and the truth keeps unfolding. [PS: I don't know if this is a harem story, so just keep reading and see. Of course, this is a very wholesome novel!!!]
