TLDR- I became more and more confused as it went on.
Spoilers below

Truly, there was no plot line whatsoever. A very rushed build up for ki jin and yeon woo…

Nothing is explained. There seems to be a big moment about to happen and it always cuts away. It’s very weird editing and nothing adds up. I really got lost by the end!! The actors were great and this had so much potential… :(

All in all plenty of plot holes but I enjoyed it because I am a huge fan of bumjun from 2z (his smile ?).
