This is a story about love and friendship, where the characters are given a chance to reconnect in a second life as they were separated in the first.

Pros:
1. The plot is unique and not something you see in every other drama.
2. Characters are all fun and interesting. Even the FL who is a fangirl never puts up with mistreatment from her idol. No super annoying airheads here.
3. The story has some supernatural elements and two timelines, which are well put together and doesn't get messy.
4. Acting is top notch. Our leads are experienced and wonderful actors who really brought the characters to life.
5. The friendship between the three MCs was so true and heartfelt.
6. The sacrifice of love the leads had to make the first time around is heart wrenching and its so good to see them get a second chance.
7. Best kiss scene in Kdrama history. I haven't seen anything better and I've watched a LOT of dramas.
8. The ML is just way too sexy.

Cons:
1. The FL is much older than the ML and 2ML, and she is portraying a person much younger than them which seemed odd to me.
2. Although I had a pleasant time watching the entire show I didn't feel the suspense or thrill elements from the flashbacks. The story was nice enough but I wasn't ever too invested in it.

Overall I'd recommend you watch this if you want to watch something new and interesting which still features love and friendship.
