Can a relationship that started with lies lead to true love?
Kindergarten teacher Shen Qiujun lived an ordinary but fulfilling life until that afternoon, architectural designer Xiao Qingrang appeared in front of her. On the screen of her mobile phone was a girl who looked strikingly similar to hers - Lin Jianyue, the late fiancée of his younger brother Xiao Yu.
In order to help Xiao Yu, who is trapped in the shadow of the past and unable to extricate himself, Shen Qiuyun signed a half-year agreement: as "Lin Jianyue's cousin", she will enter the world of the broken genius painter.
She came with a mission, but gradually discovered that the gloomy and taciturn man had the most delicate tenderness and the deepest trauma. He would stand on the cliff in the rainstorm, and make a cup of coffee for her just right in the morning; he would be in a trance because of a similar look in his eyes, and he would show a long-lost smile in front of the children.
When the agreement expired and the truth was revealed, Xiao Yu asked with red eyes: "What is true in the past six months?"
Shen Qiujun couldn't answer. She only knew that under the sunshine of the North Sea, in front of the children's drawing paper, the moment he picked up the brush again, her heartbeat was out of control.
"Seventeenth" - There are only twelve months in a year, but some people and some feelings, like the extra month, do not belong to any season, but they change the trajectory of life forever.
