After moving on from her heartbreak, we see Yumi (Kim Go Eun) and her colorful cells deal with the courage to step out on her own as a writer as her new romance blossoms with Yu Babi (Park Jin Young).

The arc that bridges Yumi Cells 1 and 2 felt natural. In season 1, Babi has been around as her coworker but he never was presented as another love interest option for Yumi. So after breaking up with Woong and we see her moving on, Babi’s presence just fits as someone who is there for Yumi. The flow of both relationships were just as refreshing because Woong and Babi’s personalities were very different. I also appreciate seeing a more dynamic journey of Yumi as a writer since it was always been her dream.

Although I think season 1's cells were more charming, there are still hilarious, emotional moments. Also, surprisingly naughty moments between Yumi and Babi's little cells, I love those! XD That's a testament to how vibrant Yumi and Babi's chemistry were. I love every time he convinces her in his blunt and swoony manner, and when he was so sincere when he takes care of her. What I don't understand is the annoying side characters and the conflicts that seem to stem from out-of-character decisions, which makes me upset till the ending. Other than that, Yumi Cells 2 was cute and I will cherish all the sweet moments! :)
