An unexpected help made the inconspicuous Su Yan fall in love with Gu Chen, a famous figure in school.
Gu Chen was sunny, helpful, and kind-hearted. He was a being that Su Yan could not define with all the beautiful adjectives.
He tried his best to enter the Gu family just to get closer to Gu Chen.
In the Gu family, he met Gu Chen's older brother, the eldest son of the Gu family, Gu Shen.
Su Yan willingly made a contract and became lovers. Since he couldn't get Gu Chen, Gu Shen, who had a very similar appearance, was not a problem either.
It's a pity that Gu Shen is getting married soon. However, Su Yan received an order to take Gu Chen as an intern for three months.
After spending three months together day and night, Gu Chen was attracted to Su Yan. When he discovered that Su Yan seemed to have someone he couldn't talk about, he attacked decisively without hesitation.
Gu Chen was disheartened until he discovered that he might be his brother's substitute.
As the wedding approached, Gu Shen realized that he didn't want to get married. He found Su Yan to confess his feelings, and unexpectedly discovered that Su Yan was actually dating his younger brother.
Only then did he realize that to Su Yan, he was just a substitute for his younger brother.
Where should Su Yan go?
