The original is better imo. There was something about the sillyness and slapstick nature of kdrama that made it work. ML in kdrama was written well and made likeable. This show has not really redeemed him and it was "put them together 2 together just because. So watch it as just another show forget the other show! Now as a show:

The trip in kdrama when they bond and talk like old friends made me ship them. We didnt really get the long sweet moments of just and FL was in love with younger ML.

2ml and 2fl are strong characters and shouldnt have been cast as seconds. I feel they got a bit more airtime than they should have. A lot of scenes of them talking about the other two instead of more scenes of ml and fl just ",hanging out". I see why people have 2ml syndrome. We just didnt get enough of ml and fl chemistry. I even didn't see why he left 2FL. It was just a bunch of weirdness!
