On an autumn night in Hangzhou, a late-night WeChat message broke Lu Shiyan's peaceful life.
A year after he broke up with his ex Su Qingyan, he always kept her WeChat messages, thinking it was just to show respect for the past, but unexpectedly it became the most secret rift between him and current Lin Wanxing.
After Su Qingyan suffered the betrayal of her new love, she turned back with broken obsessions and pressed forward step by step with the "100 Little Things in Hangzhou" that the two had agreed upon back then. Lu Shiyan swings between guilt and responsibility, and the boundaries gradually blur; Lin Wanxing wakes up between trust and disappointment, guarding his love with illustrations and bottom lines.
When old dreams flooded out of the undeleted dialog boxes, and when the current gentleness intertwined with the ex's paranoia, Lu Shiyan finally understood: real growth is not to choose between two people, but to learn to be responsible for one's past and to be loyal to the person in front of him.
This is a story about emotional boundaries, self-salvation and letting go of obsessions. It is also a dilemma that every urbanite faces when it comes to loving and being loved.
Intent: "Undeleted Dialogue Box, Dilemma of Heartbeat" uses urban emotions as a carrier to explore the core propositions of emotional boundaries, persistence of responsibility and self-salvation. Through the swing between the tenderness of the current male protagonist Lu Shiyan and the paranoia of his ex, it shows the struggle of guilt, escape and growth; through the transformation of the ex Su Qingyan from being dependent on others to being independent and self-consistent, the original family trauma and lack of self-worth behind the "obsession" are dismantled; with the sobriety and transparency of the current Lin Wanxing, he interprets the true meaning of "trust does not mean no bottom line, tolerance does not mean no principle" in love.
