After losing everything, young Roen finds solace in Pauline, a girl who becomes like a mother to him. Her departure leaves a void—until Roen awakens to the power of mana, discovering he can not only sense it, but also perceive the mana of others. Through this newfound ability, Roen continues to feel connected to Pauline, believing they are still together in spirit.

But that fragile comfort shatters when Roen encounters her again— not as the noblemaid he thought she had become, but in a truth far more devastating than he ever imagined.
