A list of Four

Alex invited the Crown Prince in, letting him into his room where the other two elders had already arrived.

The crown prince had come to visit him a few times during the first month, and then twice in the 2nd month. In the third month, he visited not a single time. 

He had yet to visit him this month either and at this point, Alex had simply stopped expecting for him to come. However, it seemed he had come this time around 

"Your majesty," the crown prince bowed in his presence. "I hope you've been having fun. You must've felt alone with me and royal father being absent for quite a long time."

"I can't say I have been lonely, but I've certainly missed the occasional company, Prince Fangyu," Alex spoke. 

"My apologies," the Crown Prince said. "But I hope you haven't been bored in this time, however. I heard you've been visiting quite a few of the royal schools."
