After a sudden accident, airi woke up from a 15-year slumber. Everyone, including her friends, had grown up, and she was confused by the passage of time. Her heart, however, remained the same as it was back then. Just as she was feeling this way, her first love, a classmate, appeared. As airi interacted with him, she gradually regained her memories. The two, who had been separated, slowly and gently merged together. The person you've always loved is right in front of you. Touching, exchanging words, and cherishing the happiness of loving each other. Hugging tightly, over and over again. Holding hands, sticking close with hot bodies. Tongues entwined in pure love sex. Slim body writhes in ecstasy. Becoming an adult feels so good. I'll always love you from now on...
