Pros:
1- The cast is just epic, the supporting roles gave me goosebumps.
2- Eun ha(child of ml and fl was so cute).
2- Story was realistic and not over the top romance.
3- No love triangle bullshit.
4- Characters was just perfect for my taste.
5- Good amount of romance with thriller episodes.

Cons:
1- As the title says it just went a bit to long at times.
2- Flashbacks where repeated to often .(Maybe since I binge watched it it felt unnecessary).
3- I lost the thrilling factor at times.
4- As the father of ML was given such importance they should have given some more information or story about ML's dad and mom.
