I feel that there is a chance for a season 2 because, if we talk about the ending, it was tragic as expected— they showed he died, but they didn't show his funeral or anything. So, there's a 50% chance he might be cured or that he could have died there. However, in earlier episodes, like episode 7 or 8, when he took his medicine, he seemed to feel a bit better. Overall, the drama was truly fantastic and awesome, except for the ending. I really loved it.
