Before the drama came out I watched the trailer and it gave me the vibe of the music video of the song Take on Me by A-ha which I love that song. I am a huge fan of Lee Jon Suk and have seen almost all his dramas so I decided to watch it. I wasn't familiar with the main actress but when I saw her I liked her acting. I especially love the the song Where Are U by Jung Joon Young every time that song came on I knew something good was going to happen. The effects were very good especially when they transition to the real world they were nice and clean. They looked natural which is something hard to find in dramas sometimes because they look fake. The first time Lee Jon Suk's character stepped out into the main actress world was just so beautifully portrayed. I definitely enjoyed the scenes where Lee Jon Suk's character started to realize in the world he lived was not real the emotions he expressed were very believable. It certainly was very entertaining and had some funny elements especially in the first episodes the restroom scene. I won't spoil it for you guys but the people who have seen it will understand what I'm saying. Although Lee Jon Suk is a very good actor in my opinion and he has shown various expressions throughout his works. There is a specific scene more towards the end where I feel like he could have expressed his sadness more. If you have seen his earlier work I Hear Your Voice in the last two or three episodes where the main lead actress gets in trouble. He talks to the antagonist on the phone and Lee Jon Suk goes ballistic he starts screaming like mad because he is afraid and he is frustrated. He perfectly portrays someone who is caught up in a situation like  that when it involves a loved one. But here in W when that moment happens something sad happens and he talking to the main girl's father he didn't show much emotion. Especially after a moment like that when it happens to someone they show a lot of emotions. I didn't see that he fell flat for me in that scene. Other then that scene I enjoyed him greatly in the rest of the drama. I also enjoyed how people in the main girls  world people kept on commenting how he looked like a manhua character which I found rather ironic it was like fourth wall broken kind of stuff. Although the song I mentioned earlier is the only song I listen to on repeat all the time it doesn't mean I don't like the other songs. I am very obsessed with the instrumental songs. The soundtrack is very good they played the songs depending on the mood of the scene spot on. I will admit I did not care for the girl from Lee Jon Suk's world. I felt like her character was bland and I wasn't impressed they could have developed her more and given her a back bone. The  bad guy does something later that really creeps me out to the main protagonist dad that was scary to look at. When I would see it I always covered my eyes it wasn't scary per say but it was not a pretty sight and it was not a resemblance of a human. Another thing that I felt was kind of flat was the romance between the main characters. I don't really see how it happened with her yes but she technically had a part in creating Lee Jon Suk's character development and his world. But for Lee Jon Suk I don't really see it. Another thing is when he falls in love with her again I didn't enjoy how he found out again it kind of reminded me of the amnesia troupe and I have always hated that plot. Although there were a lot more reasons why I liked the drama compared to the few reasons why I didn't like it. I would not rewatch it not because I didn't enjoy rather I'm the type of person who watches dramas one time and I move. I can listen to soundtracks on repeat for days however it's rare if I rewatch a drama. Other then those factors the storyline and plot was good I enjoyed how there was some twists and turns throughout the episodes. I remember  in the last maybe one of two episodes of the final they definitely got us with a twist I was full of emotions I was scared of the ending and my heart stopped but then ewe ending up having a happy ending-ish.
