Searching for his missing father, maybe?
But jin-woo thinks his dad is dead but if he sees that it isn't true then he won't quit.
I think he still has to do what the system tells him to do, so I guess it will give some mission regarding the ants, now
I'll give you a clue. In the infamous words of spindy-san "with great power comes great responsibility"
Ahhh i forgot about that:( thanks for reminding me
yeah, in the novel he ends up being dragged into the world’s hunters but his goal is basically to figure out what the system is, and when he DOES in the novel it creates a new goal
But, if his wish already fulfilled (his mom cured), will he keep trying to get stronger, or quit? Oh, or maybe he'll get another reason..
