"Are you having a party?" Leonardo asked.
"Nope. It's just a normal gathering, but we were so engrossed that we forgot the time," Chen Zhao said with a smile on his face.
"If I recall correctly, you've only been here for less than three months, right? Look at how many friends you have already! I grew up in Los Angeles but only have a few friends."
"You're my friend, too," Chen Zhao said, smiling.
David also put his hand on Leonardo's shoulder. "Buddy, we're friends now as well."
"Err... My birthday is this weekend. Can, can you attend my birthday party?" Leonardo invited, looking somewhat shy.
"Of course. Can all of us go?"
"Yes, all of you are very welcomed! I hope that you'll all be there."
In fact, Leonardo had knocked on Chen Zhao's door just now only to invite him to his birthday party.
However, he did not expect so many people to be present.
