no one knows if its good yet but i guess we can make assumptions. IU is known for only choosing wonderful scripts and after BWS massive success in LR, there is no way he would choose a bad script. Also, this script has already won awards.
by episode two i was saying "this is ridiculous" every 20 minutes... but yes. i watched it till the end. the ridiculousness was that good. it was so mind bogglingly stupid that it was good. also, the actors did absolutely phenomenal.
To anyone who's read the manhua, can you tell me if it's more Hidden Love/ WIFTY where it's lighthearted or more passionate and emotional like the First Frost??
