How to seduce a lonely married woman

She married her husband Haruo after a company romance, and Anna retired from work. This is the second wedding anniversary of Haruo's favorite hamburger steak, which he spends his second wedding anniversary. As she looked at the glass filled with her special wine, Anna felt Haruo's heart separate from her. Before you know it, Anna has fallen asleep, and wakes up on the intercom and finds her former subordinate Yuto, holding her drunk husband's shoulder... After a long time, Yuto was reunited, and was deeply angry at Anna's lonely appearance, who had once been in love with him.
