Everyone is commenting on how Ahjussi needs to be more expressive. You have to keep in mind, tho, in Ahjussi's line of business being emotional or expressive can not only be a sign of weakness, it can get him targeted or killed. I totally agree that cinnamon roll needs more comfort and reassurance. I think Ahjussi needs to improve his emotional work-life balance! So he can give Euijoon what he needs without losing himself or his street cred.
