I decided to sleep on this before I even attempted to write a review because there was just so much to process! Easily put, this drama was ABSOLUTELY AMAZING. I'm a fan of Jang Nara and admittedly not as much for Seo In Guk, I only really knew him from his Master's Sun time, but these guys...this story... oh man where do I start... Okay, so they've been promo'ing it as a rom com, but really the basis of it is a crime procedural with sprinkles of fluff, but don't be scared off, you'll be so into the main story and the cases that the sprinkles of fluff we get are short and sweet...and realistic.. This couple, their trust and faith in each other is developed so nicely that if anything, I'm glad there isn't toe curling fluff in it! (not gonna lie, when they do have cute bits, its definitely cuuuute). No joke, this drama had me on the edge of my seat from the very beginning, its been a long time since i've stayed up till 4am to watch a drama because the cliff hangers are just too good!! The mix of human nature, our childhood experiences, what makes us who we are, different scenarios that affect how we grow up and into the people we are as adults are only parts of what are explored. I loved loved loved the fact that we got such an indepth relationship with all the characters, no one was missed out, they all had their own storylines, all of which made me wonder 'ohhh thats probably why they did what they did' or 'your one action affected this entire thing'. Even though, you get whats basically expected in a crime drama, there are killers, a lot of corpses, killing, blood, weapons for murder, but It's been interesting that for once, I couldn't have predicted what was going to happen, they dropped the most shocking moments and turning points of the story that its left me :O for most of it. Each case was exciting to watch as you attempted to solve the crimes alongside the characters, whilst having an ongoing mystery that started at the very beginning and weaves itself in and between cases all the way through to the end. The acting was awesome, I'm so glad the actors and actresses took on their roles for this drama as I couldnt really imagine anyone else doing them, the antagonists in this, even though I know the character isnt really but their facial expressions still gives me the chills when I imagine them! The actual songs, were a nice accompaniment to the drama scenes but to be honest, i was too sucked into the storyline to have noticed and paid attention to them enough...! The instrumentals for scenes in this drama did its job, my mood instantly changed to fit the scene as soon as they came on, exceptionally chilling in the suspenseful scenes and then light in their cute moments. So maybe i was a teeny tiny bit disappointed with the ending, not to say i didnt like it. I was satisfied that the ending chose to give us a more meaningful end to the drama, but the with suspense that was building up i thought we were going to have some really dramatic cliffhanger of an ending. All in all i could accept their ending :) For me, no storyline or character was left unanswered so that was good. Overall, this drama was refreshing, with a thriller, full of suspense, psychological crime drama that weighed everything out a bit with their fluff moments that created an amazing storyline to follow. One that I didn't get bored of, rather was addicted to from start to end, and even after you end up thinking more about the messages they left behind the actions that happened during the drama. I would definitely rewatch this again! I've seen some epic and better used words and descriptions for reviews on I Remember You down there, but I had to express my feelings on this... :')
