Korean Drama 'Yumi's Cells' combines masterfully animation with a fluffy and yet realistic love story.

The animation, first of all, was a hit or miss, and they did a great job creating this fun atmosphere that was both funny and necessary for giving an insight to the characters' thoughts and what motivated them to act as they did.

In addition, the love story was pretty sweet, with plenty of cute moments and a realistic outcome, that, however, will probably be better resolved in the second season. The whole drama of the love story was nicely embedded to the progress of the relationship and it was pretty realistic.

Finally, the performances were all great and the animation well made.

So, overall, 8.5 out of 10.
