They found Cain so annoying (me too) by referring himself as Cain every time he speaks as first person. At first it wasn’t even a thing that attract attention,but it’s getting annoying for acting cute which he wasn’t cute at all, they mostly asking Cain to act normal just like how he was when Jooin left the airport where Cain from acting cute to the real him.

I'm still honestly thinking Cain is like Jooin's dog from the past or some shit. Honestly really don't like him, he's very...suspicious. He seems two faced and is hiding things. At least kitty sunbae is straight forward.
But I'm more of a cat person anyway.
