-If those were the casts, I wouldn't even remember the plot and the only think I could think of is probably about how handsome they look..

-No.. Song Joongki doesn't suit Yoo Deokhwa's character..

-I personally think the original casts are already good enough..

-I like the current casts..ㅎㅎㅎ

-Their visuals are really good, but I like the current casts..

-No one can suit the Goblin's role better than Gongkkaebi..

-I personally think the current casts are better..

-I think the viewership ratings will be higher if these were the casts!!

-It's possible.. But the current casts are already good enough..

-Whoa.. The whole drama would look like a movie if those were the casts..

-Why.. I like the current casts..
