Because the ml in the 3rd season is supposed to be younger than her so why would they cast a seasoned actor ?…
There are many seasoned younger actors like lee dohyun, kwak doyeon, yeo jingoo etc. His acting is not even up to par with the actress. Maybe his acting will improve by then.
i am loving this drama. i know people are complaining about the ML and the FL but i really like both of them. the ML is doing a great job portraying a different character
