In my opinion, Cirrus is jealous of Chan il not bc Skylar likes Chan il but bc he knows that Chan il is a likeable person. "What does he have that I don't" Cirrus isn't fully aware that he has a horrible personality, he thinks that he is normal and Skylar is the weird one bc Skylar was able to tell that he was putting on an act.
