Qie Xieling didn't need anyone to tell him that Luo Muchen was holding a grudge and used this to get back at him for something.
Well, he couldn't really pinpoint the crime because he had committed so many of those. As an unremorseful little milk dog, he retaliated.
"Uh Mu Mu, why are you being like this? We are camping buddies yet you would hold such a petty grudge," he said walking closer and Luo Muchen took a step back closing the water bottle having drunk more than half of it.
He didn't know why he suddenly wanted to mess with Qie Xieling. All he knew was that he got so annoyed by him and walked away but when he realised he was being unreasonable he brought three bottles of water because he knew Qie Xieling could only be with Bo Ailun and came looking for them.
When he saw the two of them hugging he suddenly had the urge to mess with Qie Xieling and didn't give him the water he brought.
