I have not read the Webtoon, so I can only write based on how the drama, not on how well it matched the original story. That said, I know some of the plot points that were supposed to happen.

I will say the actors made the show come alive, I think they did a great job playing their roles. I know Kim Go Eun is a great actress and she delivered, but I am particularly impressed with Jinyoung's acting. I think he did above and beyond acting as Yu Babi, he made it hard to me to see him apart from his character.

But for the story, I think it was a bit lacking. Like many shows it started off great, it was delightful and I found myself laughing from episode to episode, I was excited for Fridays/Saturdays because new episodes came out, but after the inevitable break-up episode, the show was not as entertaining. To say the least, there was a push and pull between the characters and the show drags out a bit. That being said even if the show dragged a bit towards the cells made the show worth it. It was interesting to see them take on how humans interact and operate, and the cells were honestly the comedic relief that was needed. The cells made the show 70% worth it for me in the end.

I do think that there were some flaws with the characters that made the show frustrating but still engaging. I can't say I agree with all of Yumi's decisions, watching her at times was a bit frustrating. But I guess it just shows that she is human and not supposed to be the perfect main character, and I can appreciate that. And also Babi was very vague from start to finish, even from his cells' point of view, there is not much to Babi, and I still think that after finishing the show.

I don't want to give the ending away, but I felt like it was lackluster. I know how the Webtoon ends and I think the writers wanted to make the ending follow the Webtoon, but also not follow Webtoon exactly. But the way that the show ended was unsatisfying. I know that some people who read the Webtoon thought it was a good ending, but as a sole watcher of the drama, it was just bland. It had some sweet elements, but I think it could have been executed better.

Honestly, I think this show, at least this season, was just a 7.5, it was an original idea, but it wasn't executed well. This is nothing against the original creator of the Webtoon, but honestly speaking, even if I read the webtoon I think I would still rate it the same.

Overall the cells made the show worth it, but about halfway through the show it dragged and was a bit frustrating.
