Korean Drama "Yumi's Cells" follows the same pattern as the one in the first season, however, this time, it fails to deliver.

The drama does have good performances that save the show, as do the cute cells that do what they do best, they offer solid comedy when it's needed. They are also well-made and nicely inserted into the story.

On the other hand, the story was messy and boring. The love story was just okay, but it wasn't as original and realistic as the first one, especially due to the unnecessary drama that was added to the love story.

So, overall, 5 out of 10.
