And I don’t get why Taehae is acting like loanshark what is the point of this

Someone in the comments said it could be so he’ll get his new girlfriend to pay the debt off and the fl can stop working so many jobs

Dude Taehae can pay all Korea's debt if he wants to

Yes…but I’m sure it’s more to make him pay for it since it’s literally his debt that he should have been paid. But since he doesn’t have money for it he’ll most likely make his new girlfriend pay.
