I liked every little thing about this cute series. I have read online that there will be a season two, and that excites me greatly. The acting in this show is spot on. The cast is fantastic.
One of the best parts is Ahn Bo-Hyun! I had previously only seen his acting skills in Itaewon Class, and BOY did he do a good job on that one. I HATED the guy! Haha.. It was a wonderful thing to see him in this show, where he plays such a sensitive, flawed, vulnerable and real human being. His acting skills are top notch. (currently watching Her Private Life, just to see a bit more of him)
I highly recommend Yumi's Cells to anyone interested in KDramas. Don't feel silly about the animated parts- just go with it and let the Cells help tell the story.
