Cheng Yi, who has a passive personality, was accidentally involved in three complex emotions.
The persistent and lovely Su Li teaches him how to cherish with her expectations and disappointments; the playful and proactive Xia Ran uses her bravery and fragility to teach him what protecting is; the innocent and emotional Jiang Wan uses her longing and fear to teach him what heartbeat is.
In this series of intersections and events, Cheng Yi continued to explore and gradually grow up, finally tearing away the fog of love and seeing clearly the true desire in his heart. He, who had always waited passively, mustered up the courage to pursue true love for the first time.

When three girls representing different futures and possibilities stand at the end, every heartbeat and every decision he makes will lead to a completely different parallel trajectory. This time, he will take the initiative, but the ending of the story will be chosen by you...
