A bar-restaurant owner by profession, Bai Lang finds himself facing his most dreaded fear when his sister drags him to the dentist to get treated for his toothache. At the clinic, Bai Lang is assigned to the cold yet charming Jin Xun An, the head dentist who seems rather reluctant to examine Bai Lang.

The following day, Bai Lang decides to prepare a special seafood risotto to express his sincere gratitude to Jin Xun An. However, upon offering the meal to Jin Xun An, all he receives is a cold response in return.

One evening as the bar is going about its usual round of business, one of Bai Lang's employees, Alex, finds himself in a situation he never saw coming when one of the customers takes hold of Alex and kisses him in front of everyone. It turns out the troublesome customer is a bratty boy by the name of RJ. Meanwhile, Bai Lang, in the face of Jin Xun An's constant persuasion, decides to bolster up the courage to return to the dental clinic.

In a surprising turn of events, RJ is now hired to work alongside Alex at the bar who appears to take a particular interest in guiding him. In the meantime, Jin Xun An seems to have gotten ill, and Bai Lang decides to go over to check on him.

Upon learning Jin Xun An had been emotionally hurt in the past, Bai Lang becomes adamant about uncovering the reason behind it. Meanwhile, Big A, the youngest dentist at Jin Xun An's clinic, finds himself crossing paths with a peculiar patient who has apparently been assigned under him.
