Yu-kun, a student living in a school dormitory, is preparing for his graduation, which is just a week away. As he reflects on his journey through the years, he remembers the constant support of his mother, who has been by his side through every challenge. The warmth and encouragement from his mother have always been a source of strength for him, especially during his time living alone in the dormitory.
As Yu-kun's graduation approaches, a new presence enters his life—Ray-san, a new tutor who is soon to become more than just a teacher. With her guidance, Yu-kun finds himself not only improving in his studies but also growing closer to Ray-san. Their relationship evolves beyond the classroom, eventually leading to a proposal that surprises and delights Yu-kun. He is overjoyed, especially as his mother becomes a stepmother to him, adding a new layer of familial connection and happiness.
On the day of graduation, the emotional farewell at the dormitory is bittersweet. Yu-kun feels a deep sense of gratitude for the love and support he has received throughout his school life. After the ceremony, he returns home, where his mother greets him with a warm celebration. The joy of reuniting and the excitement of this new chapter in his life are heightened by the affectionate and intimate moments shared between Yu-kun and his mother.
As the days pass, Yu-kun's life transitions from student to adult. He moves back into his family home, where the familiar comfort of his mother's presence continues to nurture him. The bond between Yu-kun and his mother grows even stronger, symbolizing a deep and enduring connection that continues beyond graduation, into the new adventures of adulthood.
