Watashi no Mama wa Mano-kun desu.

Following the tragic loss of her mother, Mizuki Kamo has shouldered the heavy responsibility of raising her younger siblings entirely on her own. As the eldest daughter, she has naturally become the pillar that everyone around her leans on for support and guidance. Yet, beneath her dependable exterior lies a quiet, unspoken yearning: she desperately wishes for someone to nurture and pamper her in return, offering the comfort she constantly provides to others. Her life takes an unexpected turn when she crosses paths with Mano, a strikingly handsome colleague who possesses a remarkably gentle and maternal nature. Despite his outward appearance, Mano is endlessly caring, patient, and tolerant, radiating a warmth that immediately puts Mizuki at ease. Overwhelmed by his comforting presence, she finds herself unable to hold back her feelings and blurts out an earnest plea, asking him to be her mother. This spontaneous confession sparks the beginning of a deeply heartwarming and romantic comedy, weaving together tender affection, lighthearted moments, and the sweet joy of finally being doted upon.
