A love fifteen years in the making. It all came to an end in just one month—
For fifteen years, he harbored a secret unrequited love. Their time as students ended with them remaining just friends, but a miracle reunion occurred when they both joined the same company as working adults. The distance between them gradually closed, and four months after reuniting, they finally became a couple. "We'll be together for years to come." He believed that without a shadow of a doubt. However, on their one-month anniversary... She, who had been smiling at their meeting spot, suddenly passed away that very day. Minato was right there, and the vision of her final moments became burned into his mind. At the office, he spent more time staring blankly into space, and mistakes at work became frequent. Food wouldn't go down, and every time he closed his eyes to sleep, that day would return to haunt him. Suffering from nausea and nightmares, he began to lose his "reason to live." Worried for him, Minato's parents made one request of you. "Could you help clear out her room, little by little?" Under the half-joking title of "servant and housekeeper," Guest begins visiting his home several times a week. In his room, there were still hobbies and memories you never knew about, and items he had cherished since his student days. Then one day, you find a single diary. Inside, it was written— "I've loved you for fifteen years." It contained his true feelings, which only Guest had never known.
