This drama was so amazing, and such a delightful watch!! I fell in love with the plot, the characters, and felt so invested into this world of mystery and romance. I picked this up on a whim, but I'm so glad i did! Story: The story was extremely captivating, right from the start! Not only does it get me thinking about someone's memory resetting every night, but I was always in love with the mysteries. Unlike other mystery shows I've watched, there were deeper meanings behind the ones here; all heartwarming and amazingly done. Everytime I was SURE my logic made sense, the writers go and blow my mind. *mind blown*. The humour was always a great touch, and i fell in love with all the characters, especially the supporting ones. Acting/Cast: I was extremely happy with the casting. Not only did the main leads have undeniable chemistry, but their individual characters were quirky, loveable, and believable.. despite how weird they are. I'm not extremely into J-dramas, but I hope these guys are famous actors, 'cause they blew my mind with every task and challenge. Music: The opening and theme song were both really, really, REALLY catchy (I'm singing it in my head as i write this!), which is always a nice addition, haha. I didn't pay attention to the insert songs or the instrumental tracks at first, but I started noticing how delicately it was placed for specific scenes at specific times. The editing was done really well, and the music was just overall a nice touch! Rewatch Value: I think that this is a type of drama to re-watch on a nice fall day when you're feeling like a detective. Episode 7, in particular, was one of my favourites, so I would watch that, but I don't think I would re-watch the entire drama. Overall, i had a blast watching this, and I'm missing it already. I wish it was longer, though!!!
