I felt that the actors did a good job with what they were given. The concept of the "cells" was cute, but as we move further into the drama they are used more and more, and I felt it got very repetitive as a means to make more episodes.

My biggest problem with the show was the characters. Yumi - we are told that this is her third relationship. I must say I can see why. She was immature and needy, and wanted a relationship just because she was lonely. I know that this is unrealistic of me, but part of the reason I watch romances is to see love develop, and I like to feel like the person has found their perfect love. This was a case of "love the one you're with". I also have a problem with people having a physical relationship when ultimately the relationship doesn't work out. That just takes away the "specialness" in showing physical intimacy as part of a love relationship. Ku Woong - why they made him so scraggly looking is beyond me. He was emotionally stunted and wasn't willing to stand up for the relationship. Seo Sae Yi - Ku Woong's "friend" that wanted to be more. She was manipulative and worked hard to destroy Yumi and Woong's relationship, and Woong let her. Ruby - just overall irritating throughout, with the high voice, trying to be cute.

We were led to believe that the couple fell in love basically by looking into one another's eyes. I didn't feel that they had a strong emotional connection, and I didn't feel any chemistry between them. Throughout so much of this show I wanted to yell at the tv "just say something!". There was an inordinate amount of time of staring into space, or staring at one another, to the point that I felt like they just forgot their lines.

Big spoiler here - oh my gosh, the ending! I sat through hours of a relationship that I didn't really believe or care about (because I'm not a quitter!) to just have them look at each other, unemotionally, and agree to break up, and then go their separate ways. Needless to say, I won't be watching the follow-up to this show.
