The boozy fellow strode straight towards the girl in the white dress upon entering, presumably her name was Shuang'er.
The most embarrassing scenario at a nightclub is when the girl you've selected is stolen by someone else, akin to getting slapped across the face – a big loss of face.
Even though Li Huai didn't frequent places like this, he was being blatantly provoked, something even an idiot would realize, and so, he was rather pissed off. Not for the girl's sake, but for his own pride.
Smack!
As the drunken man reached out to grab Shuang'er, Li Huai hurled an empty wine bottle at him. It missed, but successfully riled the other party.
"Fuck! You dare to throw a bottle at me? Do you know who I am? I could have you arrested right now!" The drunken man barked like a mad dog.
