I agree with you. What I notice from JayK is, he is a person who want to be in a safe state, trying his best to show just his best side and hiding his bad side. He is doing that by not revealing other members' bad side hence they also give him a good comment. In one of run episodes, there was a question about what is the most important things that a man should have? And his answer is "I think all man in the world is great". And I was like, "What?"
In other episode, the SPY episode when they confront each other at "of course" game, he just said he did not have any complaint toward JayHope meanwhile other pairs were going crazy to reveal their bad sides. At one radio interview, when Zhoungmi SJ asked him about who is the most handsome member, you know what he said? Yeah, he said "I think all of them are handsome" and the savage Yo0nGi said to him, "Don't lie! Just said JayHope is ugly!"
I think he is a very good person to keep his card.
