I think this show should've been re-written for a younger audience and the actors should've been younger age group. I'm going to keep my review short as I am still debating on whether or not to drop this show.

The "cells" are cute but I'm wondering if they're beginning to outgrow their usefulness on the show. I do love the actors but I'll say this more about the writing direction and storyline. It's getting kind of tired seeing the FL have continuous trust issues. I feel like this show is dragging on and on about the FL's trust issues. They rushed through the development of the relationship I think... it was basically they fell for each other, (which was sweet and romantic), and suddenly fast forward on showing the numerous dates they were having and now it seems the relationship to me is lacking common sense. There isn't any real honesty or they skirt around it. The relationship is lacking some kind of depth and true growth and some serious and open-minded talks to work through their issues.

You have ML who is clearly devoted to the FL yet she continues to drag along her emotional baggage from the past and all the hurt and trust issues she had with it. It's getting kind of repetitive and boring and that's also why I feel like the "cells" are outgrowing their usefulness and "cuteness".

So far I'm watching this just to pass the time but I feel like it's being wasted. I think that women in these times, (and at that age), are more able to adapt to heartache with strong survival instincts and that your ex is just that... your ex. The past. No terrible ex deserves even a crumb of your thoughts nor should you have to compete or "prove" your worth to them. Move on already and throw out the old baggage and start with brand new luggage.

We need more kdramas about women who don't let emotional baggage weigh them down but rather use it as a tool and stepping stone to learn and grow stronger from the heartache and uplift themselves. That just my opinion.

Update: I've dropped this show after watching E12. I feel like the writing has become sloppy just to make use of the "cells" and give them some air time. It's kinda getting boring watching the two leads constantly staring off into space just to show us constantly the inner thoughts of the "cells" working. As for the relationship between the FL and ML, is like they're always taking three steps backward for every one step forward. Why would the FL even think about bringing up marriage to a boyfriend who is feeling some financial troubles? To me, that's just a poorly written storyline. It also seems like they're trying to add an unnecessary love triangle and introducing us to new but annoying characters. That's enough for me.
