"The Second Heartbeat" tells a story that begins at freezing point and ends with warm light.
Independent designer Lin Zhiyi uses a rational ruler to measure life and emotions, just to stop getting hurt. Lu Yan, an upstart in science and technology, uses endless work to prove his self-worth, but closes the door to emotion. An unpleasant project collaboration pitted two proud souls against each other.
From misunderstanding to change, from heartbeat to love, they approached awkwardly in the city's light. However, the differences in growth background, the shadow of his ex, and especially Lu Yan's inability to balance work and life, have caused the relationship to turn red again and again. When the disappointment reached its peak, Lin Zhiyi chose to separate.
The pain after separation became an opportunity for them to grow. In the end, Lu Yan learned to express his cherishment with actions, and Lin Zhiyi also plucked up the courage to trust him again. They overcame their inner obstacles and understood that love is not about finding a perfect person, but learning to use your imperfect selves to create a future worth looking forward to with another imperfect person. This is a modern love fable about healing, growth, and still choosing to join hands after seeing the truth of life.
