In a kingdom divided by class and power, Eira, a young commoner with a mysterious gift, is thrust into the dangerous world of nobles, magic, and political intrigue. Her life changes when she catches the attention of Crown Prince Alvin, whose protective instincts toward her grow stronger with each encounter. But their connection is surrounded by peril—Eira becomes a target for those seeking to exploit her abilities or harm the prince through her. From being abducted and nearly sold into a brothel to surviving assassination attempts, she faces constant threats from both the shadows of the criminal underworld and the glittering halls of the royal court. Alongside Alvin, whose cold and commanding presence hides deep care for her, Eira navigates tangled relationships with allies, enemies, and those whose loyalties are unclear. In this world, where magical restraints, political games, and whispered rumors shape every move, she must learn to protect herself and decide if she can trust not only Alvin’s protection—but his heart.

"People around me called me a sage who was obsessed with the Philosopher's Stone." There was once a man who mastered magic and was known as a sage. Realizing that creating the Philosopher's Stone was impossible with his current body, he took a gamble. He decided to reincarnate into a future world as a different person to obtain a new, stronger body. His reincarnation was successful, and he gained the body of a cute boy named Mars, marked with the emblem of strength, the "Pure Seal." However, in the future, this emblem was inexplicably regarded as a "Defective Seal"...! All for the sake of the Philosopher's Stone, the journey of the strongest sage begins anew!
