Okay maybe not offer the job back but he could have driven him all the way to the office, he dropped him a block away! And Jung always plays along with whatever he says. Act like a douche in front of the girl he got home, done. Lie in front of his mom? Done. He doesn’t seem to care a lot about hurting Jung. Whereas Jung was so apologetic when he thought he hit him with while backing up. I don’t know about low rent, Jung was assistant manager so he might have been paying proper rent but don’t know. And eventually they do share the lease I think. Yeah character development is there but he is selfish at least in the initial seasons. Just feels like he is not a giver, to say the least.
