Does no one else see it?

You can see how utterly terrifying Cain’s face is right? Also for the first time in the story (infront of Jooin) Cain didn’t refer to himself in the third person, rather saying “I” instead of the normal “Cain”. He finally goes back to his “cute puppy” persona when Jooin says he’ll consider his feelings, doesn’t that feel a little weird to anyone else?
