JUC-599 My friend's wife Nana Aida

Nana was married to her college classmate Takashi and had a happy life. Although she lives in a company house, she is comfortable and the presence of her husband's best friend, Ryuichi, who lives next door, was also reliable for Nana. One day, the news of the alumni association arrives from the circle to which Nana, Takashi and Ryuichi belonged when they were in college. Nana and Ryuichi decided to attend together with Takashi who couldn't go for work. However, it was not the memory of his old friend that dominated Nana's head at the alumni association, but his love for Ryuichi, who should have thrown it away.
