The passionate, sincere and must-have love in youth allows the male protagonist to impress the female protagonist time and time again, launching a vigorous campus love. But as time goes by, age increases, and the external environment changes, the male protagonist decides to let go and let love disappear in youth.
However, when they meet again more than ten years later, the two people, who have changed their lives, start a new story. The entangled feelings made the two people wander between memories and reality, falling in love and killing each other.
It's very touching.
