Loved the Chemistry between Kim Yumi & Ku Woong I am a fan of Kim Go-Eun. "Coin Laundry Girl", "Memories of the Sword" & "Goblin". I can't get all of her shows in USA but would watch if I could. I am a new fan of Ahn Bo-Hyundai & Jinyung park. Ever since I saw" I saw the Devil" I have become a serious k-drama fan at the beginning of our mutual Pandemic. Many shows say the actors have great chemistry but this is the first time that I Really got that this couple could be a real couple on or off the screen & I thank you for whatever your magic you really had or great acting. These days it is nice to see uplifting stories so I was so very bummed at the ending. I did not want to see this couple break up. I saw on u-tube that a character named Soonrick will appear. My vote is for Park Bo Gum. He was in "Coin Laundry Girl with KimGo-Eun & he completed his military service. I loved him in Reply 1988. He was on the list of many names suggested to play that part. I enjoy jinyoung park as Bobby in women's clothing. Especially his pinky finger being up when he drank from a cup. He was very cute is women's clothes. I listened to Jinyoung of Got7 on u-tube. What a beautiful voice. He does have a great gift & he seems to be a natural actor. His dancing reminds me of Rain, who I happen to appreciate, as an actor & musician. He also helped a lot of people with their rents when COVID began. So many dancers around the world look like Michael Jackson the OG of dancing in pop music. Rain looks original. In fact, Bob Fosse made the first moonwalk that Jackson is famous for, in an old movie called "The Little Prince"1974. Bob Fosse was a famous American choreographer in the 60's & 70's. He transformed dancing according to his own physical limitations. I also enjoyed "Ruby" & "Wook" in the show. I read that Kim Go-Eun will be playing the "Little Women". A classic. I really liked them 1933 version with Katharine Hepburn as Jo March. I read that Wi Ha-Joon will be in it. Though he is known from "Squid Games"2021 he & Lee Dong-Wook have a great bromance in the new series"Bad & Crazy", like Gong-Yoo & Lee Dong-Wook in "Goblin" 2016-2017. I did enjoy all of the Cells & maybe an emoji could be created for Ku Woong(Ahn Bo-Hyundai. I am looking forward to Season 2 of "Yumi,s Cells". Fortunately I can see it on Viki/Rakuten tv. Thank you all for great entertainment.
