My husband's friend

Akari runs a small restaurant with her husband Hiroshi. One day, Hiro was injured and he couldn't even walk. Hiro asks his old friend Sawaki to help out with the store. Sawaki is a man who should have been happy...but Akari's expression was cloudy. This is because Akari had a relationship with Sawaki in the past. Akari pretends to be calm, keeps her distance, and meets Sawaki. However, even when Sawaki became his best friend's wife, he sought Akari as hard as he did back then...
