Maybe, I think it was a type of feeling deception, as Shin was willing to become a "bad" guy as long as he was next to Jake. But it turns out Jake was actually a "good" guy already, and I think Shin got mad because he almost risked it all for nothing..
... (I don't know if I explained it right...)
I was also a bit shocked when he got mad at first....

i genuinely love shin cuh why is he looks so disappointed when find out Jack work for CIA
