Heart Beat Frequency: Two-Way Rush in Four Time and Space

Some people are hiding around the corner, spending their entire youth brewing a sentence saying "I like you"; some people pretend to be lovers, but make the fake come true and taste the sweetness and sourness; some people travel through misplaced time and space, salvaging forgotten promises in old diaries; some people hold the love formula, but can't calculate the panic cosine value when they look at each other... Four youthful love songs that began in Qingcheng Middle School spanned ten years and intertwined into a heart-beating symphony. When the secret love finally waits to look back, when the fake play finally comes true, when the future finally reaches the past, when the algorithm finally loses to the heartbeat - you will find that the other side of youth is written by love.
