This drama was very refreshing to watch. If you're sick of all the kdrama cliches, then give this one a try. A realistic representation of an actual relationship w/ just enough touches to give off that magical feel. No hidden mysteries, no overlapping misunderstandings, no tricks. Straightforward, very straightforward; creds to male lead.The chemistry b/w all cast was incredible and all characters were very well developed w/ interesting and just enough backstory. The dialogue was probably my favorite part. It was full of wits and cleverness, and props to both leads for the excellent delivery. I was very engaged with their convos, very natural and real; especially the first couple of episodes when they were just getting to know each other. They didn't talk in idioms, and you can imagine the conversation still going even after a scene is done, not just a build up to say that one catchy line that is later repeated in further episodes.The camera work was also something. There were no exaggerated replays nor hundreds of shots from different angles. It was, again, so natural. When something surprising happened you too are surprised but not because they added any special effects/zoom-ins or fancy camera flips. I wasn't a fan of the black and white though I can understand why some people enjoyed it as it served as a bookmark and made you pay more attention to that specific moment.Half way through the drama got a little bit boring but I kept up cuz every once in while they provide you with a very satisfying scene that breaks all cliches and you're pleased. The characters were also very consistent. They didn't do a sudden 180 when they got into the funk. Unlike most dramas where the leads, especially females, start off strong and hella charismatic then suddenly by ep9 they're dragged by everyone. Thats why this female lead was possibly one of my faves out there.I also like how everyone was doing their own thing. Usually in k dramas the leads start with a certain "profession" and then half way through it feels like everyone is just taking endless days off and you start forgetting what they actually did with the focus being shifted entirely to the drama and melancholy phase of cycle. They included the viewers in all of the leads professional lives and how seriously they took their jobs like one would do in real life. And, no! You won't just skip work or an important event to go do random acts of romance and god forbid drag the female lead by the arm from point A to point B stopping her from doing important ish.The inside to the writing world was real interesting. It shined light on so many hidden secrets and acts that are done in that business. The good and the ugly. Enjoyed it alot.Finally speaking, It's not like it was the best drama I've ever watched but man, I enjoyed it! The whole thing w/ the running club felt so anime and I didn't mind it one bit. The male lead is just drop dead gorgeous. And man those first couple of episodes makes my stupid mid-life-crisis-20something-ass heart flutter like crazy. I wish they dragged those scenes more. Tl;dr not the best but still a very solid drama.The dialogue is the best. Straightforward, realistic, hella cute.
