In a quiet town surrounded by mountains, where escape seems impossible, Akira finds himself caught in a web of emotions he never expected. A close childhood friend of Yuuta, Akira has remained in their hometown while Yuuta pursued a future in Tokyo. Now studying at a university and working as a national civil servant, Yuuta has taken on the responsibility of supporting his mother, who has been raising him as a single mother since their father left five years ago. Akira, still a high school graduate working in the local area, has always felt a sense of envy watching Yuuta move forward in life, even as he has remained close to his mother, who has always been a comforting presence in his life.
The bond between Akira and his mother is deep, and it's clear that she has always been more than just a parent to him — she is a constant, a familiar warmth in a life that has often felt uncertain. But when Yuuta returns from university, his mother’s health begins to waver, and Akira finds himself drawn into a new kind of connection, one that challenges the boundaries of friendship and affection.
As the days pass, Akira's feelings grow more intense, and with every interaction, every shared moment, the lines between loyalty and desire blur. His mother, once a steady figure of comfort, becomes someone he can no longer ignore — someone whose presence has always been a part of his life, but now feels even more personal. The tension between what he wants and what he has always known builds, especially when he sees Yuuta once again, still close to his mother, still the friend he has always been.
In a moment of emotional release, Akira lets go, surrendering to the feelings he has long kept hidden. His mother, who has always been there for him, becomes the one he finally turns to, and in that moment, everything changes. What started as a quiet summer in a small town turns into a personal revelation, one that leaves Akira forever changed, and his mother, who has always been the center of his world, now holds a place in his heart that will never be forgotten.
