He‘s not angry that Jake isn’t a gangster, he‘s angry because he was deceived and had his trust broken.
It's the lying, a relationship cannot be built on a lie that big. Also it seems like it was a big deal to Shin that both him and Jake were ‘trash’, both just people living a rough life, so i imagine now finding out Jake was actually some big shot CIA agent is a punch in the gut.
yes girl, i found my people. no matter how big or small, a lie is still a lie. and that what Shin is currently feeling rn.
I'm confused about Shin, why does him finding out Jake isn't a gangster is a bad thing? Isn't that supposed to be the opposite?
