As someone said in another review "Unfortunately, in retrospect, the drama overexploited the main story and, in the end, it felt like nothing really happened, just the main plot and nothing else". The main plot being "Yu Ri is back to life."

There's SO many plotholes and fillers.
- Having side ghost story is not uncommun but it's the first time I found them rushed and just there for the sake of being there. I found Kang Bin's story incomplete, same for Mi Dong who could have been an amazing side story imo ?
- I don't understand why they insisted on the whole ghost's favors thing for AGES when it was forgotten just after ?
- Guk Bong ...was there. But for what ? Nothing, he added nothing and he disappeared as fast as he appeared
- Min Jeong's character was so..empty ? It was so weird. She became emotionally capable in the last four episodes. + What is she doing all day ? She has a maid, a pick up helper, yet doesn't work nor go out. She's super "busy" for someone who has nothing to do except maybe go at the lawyer's office in the first episodes ? SeoWoo was ALWAYS alone. How come it took three nosy mothers for her to understand that SeoWoo wasn't talking ?
- The 4 last eps were crying. "I'm sorry" "No don't be" "There's nothing to do" on repeat.

I never saw a drama with SO much potential getting ruined like this. It's really like they focused on YuRi back to life and like nothing else mattered anymore. They tried adding bonus plot point but forgot about them seconds after.

I was really disappointed tbh. The actors are really a gem, but it's so so poorly written. (+ I don't even remember any of the OST)
