I think the actors know what they're doing. Im Soo Jung is an award winning veteran actress, Best Actress in 33rd Blue Dragon Film Awards while Lee Do Hyun is an award winning rookie actor, Best New Actor in 57th Baeksang Arts Awards. They're professional actors and I believe in them. They will not accept projects that will put their careers in danger and so far their previous works are quality dramas. No need to worry cos I believe them! The only reason why people complain about this cos they only want popular actors, I bet they will not complain if the actors are popular.

Don't be a hypocrite, y'all are saying that you despise teacher/student relationships but some of you can't really wait to watch Why Oh Soo Jae cos of Hwang In-Hyeop!! Anyway, for me I wouldn't mind if this drama has a romance cos in the the present timeline, he is a 22-year-old man in the story, he's not a student nor a minor anymore and I really don't care about the age gap as long as the story is good!!! And also the actor playing Baek Seung Yoo is already 26 years old so I don't see any problem with that at all and besides, he can learn a lot of things from Im Soo Jung cos she's an award winning veteran actress with a lot of experience!!!
