There might be hope since at the end of the novel, yoo junghyuk goes around with biyoo to find dokja in order to rescue him. They even gets a crossover briefly in a panel with "The world after the fall", once with dokja coming across the mc after becoming the eternal dream and another with a panel featuring junghyuk and the mc (sadly it's just an easter egg and I don't think a chapter has been released about that).
