They both had motorcycle hobbies and were close enough to go on tours together, but at the turning point of their 10th wedding anniversary, she discovered her husband's affair.

To get out of that helplessness, she tried to relieve stress by having sex with a man she met on an adultery website, but no one could satisfy her. Unable to let things continue like this, she chose to ask a professional actor as her final choice.
