My Classmate is a Widow

I'm sorry, darling... Misato, at the young age of 33, becomes a widow after her husband dies of illness. Ten months after the funeral, she receives a call from a man named Sato, her husband's former subordinate, who wants to pay his respects and comes to her house. Coincidentally, he is Misato's classmate and first love. Reunited with Sato, Misato finds herself alone with him on the living room sofa, and as she looks at her husband's portrait, she feels a small flame ignited within her.
