I'm still confused about the debt? So it was never paid off?

The other thug group paid, and absolved the original debtor, MC's father. But didn't absolve the MC, which is not valid but they are taking him hostage. Well, thug things right? （￣へ￣）

yes, the way i see it was taeju just forgot about it, like for him it was all been paid off, but formally, there was no receipts and documentation, thus, this happened.

I was thinking he was going to track down the dad and tell him to take care of his own shit. Not his sons, though he's keeping them.

yeah that too or those guys who threatens the omega, i think, he's going to transfer all of his debt to them??? lol i forgot how the story unfolds
