Many years later, Xie Yanlin returned to China to take over the family group and reunited with Lu Ting at the "Lin Yanzhu" bar. He has become a new upstart in the business world with a sharp aura, and the young man who hid in the corner and peeked at him has become a bar owner who can stand alone.
The first meeting in the box, the chance encounter in the bathroom, the brushes with misunderstandings, the dependence after drunkenness... Reunion is like a slowly fermenting wine, making the dusty secret love rekindle the warmth of drunkenness. Xie Yanlin didn't know that the red string on Lu Ting's wrist was seeking marriage for him; nor did he know that every time he casually looked at her, he would stir up a storm in the other person's heart.
When past misunderstandings and hidden feelings intertwine, the two seemingly alienated people gradually get closer through repeated trials. It turns out that some heartbeats never expire, just like that unsent love letter, which finally has the chance to be opened in the time of reunion.
This is a two-way journey spanning many years, about the sourness of secret love, about the weight of growth, and about - it turns out you are here too.
