[Chinese]JUC-599 My friend's wife Nana Aida

Nana had been living a happy life with her college classmate, Takashi, whom she married. Although they lived in company housing, the environment was comfortable, and the presence of her husband's best friend, Ryuichi, who lived next door, was also reassuring for Nana. One day, an announcement about an alumni reunion from the club that Nana, Takashi, and Ryuichi had belonged to during their college days arrived. Leaving Takashi behind due to work, Nana and Ryuichi decided to attend the reunion together. However, what occupied Nana's mind at the alumni reunion was not memories with old friends but the love she thought she had abandoned for Ryuichi.
