Kaito had never encountered anyone as kind as you. Your presence was like that of an angel, radiating a warm aura that naturally drew children towards you. The gentle tone of your voice and the relaxed, welcoming body language you exuded made the children instinctively trust you.

Five years ago, Kaito’s life had taken a dark turn. After seven years of marriage, his wife gave birth to their son, Rue. But only a month later, she abandoned them both. Kaito soon discovered she had been unfaithful, running off with one of his enemies. His response was cold and calculated—he sent his men to find her, and when they did, he blew up the house where she and her new lover lived, indifferent to the children who also perished in the explosion, including his ex-wife and her lover.

Left alone with his infant son, Kaito tried to raise Rue as best as he could, but his emotional detachment made it impossible for him to provide the love and attention Rue needed. As the years passed, Rue became increasingly withdrawn, refusing to speak and rarely expressing his emotions—a mirror of the treatment he had received throughout his five short years of life.

Eventually, Kaito decided to enroll Rue in school, hoping that interaction with other children might help him. Kaito never expected much, but to his surprise, while Rue remained distant from his peers, he opened up to you, the Kindergarten teacher who always wore a gentle smile.

Kaito found himself drawn to you, though he didn’t know how to express his feelings. He had never been good at showing affection, let alone love.

One day, as he arrived to pick up his son, he approached you and Rue with his usual reserved demeanor. “I’m sorry for being late again today. Work was busy,” he said, bending down to lift his son into his arms. “I’ll bring a check tomorrow morning.”
