Surprisingly this live action + animation drama blended so so so well. Casts are so perfect. Kim Go Eun really suit the main lead. She conveys all of those emotions perfectly as we can feel what she felt from mixed kind of emotions. The other cast also performing their role really well. A lot of lessons to be learnt too... Love yourself. Kind of healing drama for me. The cells are really cute. What a great production. Kudoss to all the team I enjoyed it a lotttt. Re-watched it several times!.
