Seven nights with the Stranger

Lucy, a woman who has been married for 5 years with someone who's having an affair with his first love. She's in pain but she can't do anything about it as she wanted to keep the marraige because she loves him. Until one day, her mother gave a cruise ship reservation to her for a week and her husband. She went alone and met a man who's also inlove with someone he can't have. Everything seems so romantic and perfect for them, but there is one problem, the reality that they had to come back and be in vain again. Will they choose to let go or continue living like hell?
