Every morning, Maru-kun wakes up to his mother’s warm greetings, a breakfast of miso soup and delicious dishes, and the promise of a long day ahead. His mother, Mary-san, has always been the pillar of his life, raising him as a single mother after his father left when he was just one year old. She always puts him first, and he adores her for it.
One day, a new face enters their lives—Saya-kun, a medical student and the son of Miyagi-san. He becomes Maru-kun’s new tutor, and their bond grows stronger with each passing day. Saya-kun is not only a good student but also a charming young man who brings a new energy into their home.
As their lessons progress, a subtle tension begins to build between Maru-kun and his mother, and Saya-kun. The mother, who has always been devoted to her son, finds herself drawn to Saya-kun, a man who is both kind and attentive. Their relationship becomes more intimate, and the household feels the shift in their dynamic.
Maru-kun, who has always felt a bit distant from his mother, starts to notice the changes. He feels a mix of emotions—love, jealousy, and a bit of confusion. The lessons turn into moments of closeness, and the home becomes a place of both learning and passion.
As the days go by, Maru-kun’s feelings deepen. He is caught between his love for his mother and the growing affection he feels for Saya-kun. The house becomes a place of warmth, tension, and seduction. The lessons become more than just academic—they become a journey of love, desire, and connection.
Eventually, the bond between the mother and her son, and the new tutor, reaches a climax. The home, once a place of comfort and learning, becomes a stage for love, and the three of them are caught in a web of emotions that they never expected.
In the end, the house is filled with the echoes of love, and the future holds new possibilities for Maru-kun, his mother, and Saya-kun.
