my husband's friend, love blooming.

He was married to his school friend Kenji. My husband has been kind and happy for a long time. One day, I happened to meet Oki, my best friend when I was a student. Oki started his own business and had an office in the neighborhood. My husband is delighted to meet his nostalgic old friend again, and encourages his wife to help him with the still unstable Oki job. I don't know if he and Oki used to be lovers. And the heart of Oki, a wild and reluctant man who was opposite to his kind husband, attracted him again.
