Lust. Treachery. Forbidden Magic.

Ehrwin's ambitionless life on Earth ended in tragedy, leaving him filled with regret. But upon reincarnating in the world of Sjethia, he vowed to make the most of his second chance. However, his new life is fraught with challenges. As a member of the noble house Bargunri, known for producing powerful magi, Ehrwin is expected to wield magic, but unfortunately, the gift of magic has eluded him. To make matters worse, as the third son, he holds little political power and is only eligible to inherit a fraction of his family's wealth. Furthermore, Sjethians inability to comprehend the idea of infidelity stands in the way of Ehrwin fulfilling the desires he held back in his past life.

Determined to rise above his station, Ehrwin takes a gamble and sets out on a dangerous journey to seek forbidden knowledge from a mysterious witch deep in the Murky Mire. Legend says the witch possesses secrets to unfathomable powers. But as he gets closer to his goal, Ehrwin discovers that the cost of this power may be much greater than he bargained for.
