I met Nao at the spring orientation after I entered university. I spoke to her when she was alone and we became friends. After school, I would sleep together with my roommate Yu at my apartment near the university until the morning, and we would repeat this routine until soon after, Nao and Yu started dating. I congratulated them sincerely and we continued to be friends, but we drifted apart after graduating from university. Five years later, I happened to meet Nao again... This is an emotional coming-of-age story where feelings that were never meant to connect come together.
