This series is quite wholesome with slice of life feels to it. Its a piece of art. We r watching this series through Yeon Woo's point of view , so we only get to know what he knows .Its like someone went through his journal and brought to life the most indispensable moments of his life. I have watched thousands of dramas from many different countries but very few have touched the way it has . There is something poetic about the way it has been. You can see the effort everyone put in it. Hats off to the director who shot this so beautifully and gave us something so precious which will be always close to my heart.

This series is a roller coaster ride of emotions one moment you r laughing n the other moment u r crying. This made me realize how wonderful it is being able to see let alone seeing colors, such a simple thing that we take for granted but there are people out there who don't have this privilege, how sad n depressive life would be if there were no colors in life, how you never importance of somethings until you have lost them, how heart wrenching it is to get something and losing it again, when you have never experienced something u never know what you have lost

Anyways, since we r watching it from Yeon Woo's perspective the way mono probe relationship is shown initially is how he perceive it to be and by the end of it we viewers along with him realize that not every mono probe is same just as not every human being is same. About color rush happening every time, when mono looks at probes face it doesn't sit well with me, why does it has to be face why not eyes, with the whole story based on the premise of being able to see colors, it would have been more poetic if the color rush were to happen every time they look into each other eyes, the light reflected from the retina of probes retina changes to a certain wavelength which when falls on monos retina activates red n green cones giving him the ability to see colors

Regarding acting, both ml were brilliant , im not familiar with any of their works before so it was my first time watching them maybe thats why i was able to see them only as Yeon Woo n Yoo Han or that actors fully immersed themselves in the characters. The way Yoo Jun has played is exceptional I liked his body language he was very confident in it he showed inner struggles of Yeon Woo real well. But with whom I was most impressed was Hyun Jun, he owned Yoo Han. The display of his emotions of want, need were so strong that I was able to them from the other side of the screen which btw rarely happens with me. For me Hyun Jun was the star of this show, you could feel his desperation, his desire to hold on. I was surprised when I saw only this project listed in acting career on mdl, I hope to see more work from him cause his talent too precious to be not shared with the world it would be our loss.

Kudos to the director, for the way he shot this show you could actually see the world through Yeon Woo’s eyes. I think the director deserves all the credits for making such a beautiful show. Though it was a risqué to shot the way he did because the audience were privy to a whole lot of information which left us questioning like what really happened to YWs mom n whats going on with Min Jae’s old man n how much progress Yi Rang made on her quest to look for her sister. But their choice makes sense with format n budget. Usually we don’t see a whole series told from a single person’s pov so it was quite refreshing too watch.

Visuals were good the way world transitions between colored n mono was done beautifully especially YW’s eyes during color rush look magnificent. Regarding color rush, I didn’t like the color scheme during the sequence, it looked, for lack of better word, cheap.

BGM was good, played at just the right places. The only issue I had was that at few places.,I couldn’t hear the actors.

Overall, it's a feel-good show to watch while being wrapped up in blanket n eating ice cream especially when you are emotionally vulnerable.
