Shen Manqi and Lu Zechuan step into marriage. Shen Manqi deeply cherishes her male best friend of many years. In their interactions, she fails to properly manage the boundaries between a friend and a partner, neglecting the sense of propriety that should exist in a marriage. Accumulating rifts cause cracks to slowly form in their relationship, and after careful consideration, they choose to end their marriage. Experiencing all of this, Shen Manqi gains new insights into intimate relationships. Lu Zechuan also lets go of the past and opens up a brand new life of his own. Both move forward separately, earnestly running toward the life ahead.
