When reckless art student Lin Zhi splashed paint on Bingshan senior Shen Mozhou's limited-edition shirt, she thought her life was over. In order to repay the sky-high debt, she was forced to become his "contract illustrator". He was harsh and picky, and she was stubborn to fight against it, but in countless late nights together, they discovered the unknown softness in each other. When the contract expired, he put aside his pride and chased after him: "The debt is cleared, but now, I want to formally pursue you in the name of Shen Mozhou." From campus to workplace, from youth to maturity, this is an ultimate romance about dreams, growth and two-way running.
