This is the best kdrama I've watched. Usually I wouldn't give a show a 10 unless it's completely flawless and really hits the feels too. But even though I have a few minor critiques when it comes to this drama, they're so minor that I decided to give this a 10 anyway.

Story: I gave this a 10. Almost gave it a 9.5 but ultimately, if you read between the lines, I think the story itself deserves a 10. All the plotlines tied up perfectly by the end, they took their time with the ending too and everything was plausible. I wasn't frustrated with the way anything turned out and honestly, even Investigator Choi's death made sense and added the right amount of angst and drama for the climax. It didn't feel like they decided to randomly kill him off to drive the ending climax either, it genuinely felt natural to the story. The characters were all really well developed and lovable, each having their distinctive personalities that really added to the depth of the story. This kdrama, by far, has the best second male lead storyline ever. Woo Tak was so kind-hearted, never once made a move on Hong Joo out of respect for both her and his close friend, he was happy if she was happy. He was honest and I'm happy that he was such a main character. As someone who HATES love triangles, I'm really really amazed with how they went about the second male lead. It wasn't really a love triangle, despite Woo Tak clearly being in love with Hong Joo. She wasn't in love with him, he didn't try to interfere or confess, and our bb Jae Chan knew about his feelings but still cared for him. The trio's friendship was beautiful and I'm glad no one was treated unfairly. All of the juxtaposition, cinematography, writing and subplots were superb. This kdrama has the perfect mix of love, friendship, family, crime, and drama. The only question that wasn't outright answered was about Hong Joo and how her premonitions started. But I'm okay with that being more or less a mystery since sometimes, you don't always get the answers you want in life. Like, how is she supposed to just magically find out how they started? If we follow Woo Tak's theory then maybe she had a near death experience when she was younger and that's how the premonitions started. And maybe she wasn't saved specifically by one person, hence why her premonitions aren't just about one person. Then she saved Jae Chan so he started having them again once they were re-acquainted. Then he saved Woo Tak, so he started having them. Either that or it's all related back to Hong Joo and that's why they started getting premonitions; because of her. They were supposed to die but ultimately didn't either, because of Hong Joo or in relation to her - since Jae Chan actually saved Woo Tak because he wanted to save Hong Joo and her mum. Therefore, since she originally had the ability to dream of future events, when the future she saw was changed (because of or in relation to her) to the point where lives were saved that were supposed to die, that's why they also gained that ability. That's just my theory though. And it's also the reason I don't mind that we never got a clear answer. Everything else was wrapped so nicely that I don't think it was due to laziness.

Acting/Cast: I really enjoyed everyone in the cast and their acting. However, I gave this a 9/10 because of two reasons. I want to first say that when I started this kdrama, I was unfamiliar with almost all of the actors in it. Now I bet everyone is appalled that I haven't seen anything Lee Jong Suk has been in, I know, but I'll get around to watching them. Anyway, the only actors I know are Kim So Hyun (guest role), the fried chicken serial killer guy, and Jung Hae In (Woo Tak). I know I'm going to get hated on for saying this but Bae Suzy's acting wasn't as phenomenal as I was expecting. Majority of the tears she spilled were fake and not genuine and her acting was a little one note. It wasn't bad by any means, but I struggled to really connect to her. Also, I really loved Hong Joo and Jae Chan as a couple. They were cute, non-toxic, and their kisses were great. However, I'm sad to admit they were lacking a little in the chemistry department. I don't know why exactly, but yeah.

Music: I LOVED the soundtrack for WYWS. Every song was perfect, memorable, and were used perfectly throughout the show.

Rewatch Value: A solid show that doesn't make me endlessly frustrated with enough angst, cuteness, and comedy to keep me entertained.
