Song Qing'er, who was pregnant, went to see a psychiatrist because she suddenly saw her sister who died when she was a child. However, the treatment did not improve her condition, and it tended to become more serious.
But her husband Lin Feng, who thought he was deeply in love with her, didn't want to have a lover outside the house, and the mistress was not a good person and wanted to replace her.
Lin Feng, who originally preferred family between the two women, developed a psychological tilt when his wife's illness worsened.
At this moment, Lin Feng suddenly discovered that none of this was natural, but that someone behind the scenes was deliberately planning for him... It turns out that we are not kind, we are all guilty people.
