"Love is the light that makes us better ourselves." Lin Xingchen is a junior student in the Department of Journalism. On the surface, she looks like an ordinary girl full of energy, but in fact she is the hidden master of Chinese style illustration "Xingchen". He has a tenacious and optimistic personality, has his own opinions and does not follow them blindly. He is a warm little sun. Lu Xubai, 22 years old, is a senior in the Department of Finance and president of the student union. On the surface, he is a cold and distant campus male idol, but on the inside, he lacks a sense of security due to his family background. Logic is paramount, except for the heroine, who has no principles. Due to an "unexpected" campus scandal, the two were forced to sign a "fake couple contract" to cope with the crisis. However, in their daily "acting skills", they faked the show and discovered each other's unknown shining points. In the end, they sincerely agreed to each other and grew up side by side.
