The story tells about Chen Zitong (played by Guo Xuefu), a taekwondo athlete who has been aiming to participate in the Olympics since childhood. When she faces the dilemma of a possible premature end to her career due to a recurrence of an old injury, she meets a young CEO (played by Wang Dongcheng) who has "hemophobia". They go from being enemies to lovers, and the two change their lives because of each other. This drama explores the idea that love is not a one-way binary question of "who protects whom", but a two-way comparative question of "who protects whom more".
