From the husband's pov he only found out his wife wasn't satisfied with his sex performance then when he buys energy drinks to do his wife better she is missing the very day of their anniversary while she was out the whole day fucking with the neighbor leaving her wedding ring on top of the table.
Also another lame open ending, in the last page the oldman tells the wife to go home already. And then the text says she returned past 9PM. Yes, it ends like that.
