Wait I'm confused can someone explain?
It doesn’t have a correlation to him hitting on Shin. Shin is realizing that given how serious Jake’s actual job is, then he might have meant it when he told Shin that he would always look out for him and that they were in this together. However he’s still doubtful because with Jake lying to him about his background, he mistrusts him too much to truly believe anything Jake had said to him in the past.
JUST START DATING ALREADY!!!
