Don't let the title or drama photo confuse you, as this drama is actually pretty great. At first I thought this drama was going to be a cutesy, unrelatable, immature romcom. However, Yumi's cells is not your typical K-drama, as it is realistic in almost every way possible. Honestly, it felt like this drama was made specifically for me, as I am going through the same thing as Yumi. I am in my 30's like Yumi, haven't dated in over 3 years like Yumi, work-work-work-work like Yumi, and someone is interested in my like someone was interested in Yumi, but I'm hesitant just like Yumi, and have so many questions and doubts just like Yumi. What's so fascinating is my emotions and reactions to the romantic scenes are the exact emotions and reactions that Yumi cells have, almost 5 seconds after I have mine. For example, I did a fist pump after something good happened during episode 3, literally seconds later, Yumi cells did the same thing lol. I really love the concept of how the cells/hormones for different emotions and functions in our bodies are expressed in both Yumi and the male lead, as they are dating and going through everyday life. That lust cell is real though, meaning I have to fight that urge too lol. In this drama the lust cell is super relatable, as is the rest of the cells lol (see episode 4). I am currently on episode 6, and I look forward to watching the rest of the episodes.

I've come to realize something about myself. If I ever feel or think a man is making me compete with another woman, I'd drop the relationship even if I really care about him. Someone who you are in a relationship with should never compete for your time, attention, and affection. After what happened in episode 8, it would probably be the end of my relationship with the male lead character, if I were Yumi. I 'ain't' dealing with catty women, or another woman, trying to gain my boyfriend's attention. If he doesn't handle it, I'd say bye to him too.

At the beginning of episode 9 (the first 4 minutes) the male lead gaslighted Yumi. He tried to say that he didn't tell Yumi that his ex crush and current coworker lives in his building and stops by to borrow stuff, because it would make her sensitive, like how she was being "sensitive," at the moment he got caught. She wasn't being sensitive but rather is upset at the fact that he lied and deceived her. For goodness sake he dodged her request to come over for over two weeks. He thought lying and deceiving her was better for her, then giving her a heads up that the girl who he used to like, and currently work with everyday, now lives in his building. I wouldn't trust him either. This man is more toxic than her ex boyfriend. At least her ex-boyfriend was upfront about his douchebag behavior, but this one is pretending to be a victim.

During episode 9 around the 10 minute mark when he said that he was taking care of it (meaning, handling his co-workers affection for him), he said he's doing it in a way that would not make anyone feel uncomfortable. BRUH! Why does he care if someone who he is not in a relationship with, but knows that he is in a relationship but still persist in flirting with him, is comfortable? Why would he risk Yumi's comfortability level for someone else? To make sure his girlfriend (Yumi) is comfortable, he should definitely make another girl uncomfortable by telling her TO LEAVE HIM ALONE (very sternly).

During episode 10 around the 52 minute mark, Yumi's childish behavior starts to get on my nerves. Her boyfriend wasn't putting her down but giving her his honest opinion in a respectful way. She asked for it, and if she didn't like the answer, she could have said "I don't like your answer, but I appreciate your honesty." This man ain't a genie in a bottle.

During episode 12 (the first 8 minutes), I can understand why Yumi would ask that specific question. Nevertheless, I can also understand why the male lead character did not respond right away. Typically, men like to get their self settled financially, and typically, women don't care if the person that she's dating is settled as long as she loves him, and she feels taken care of emotionally.

Episode 13 (at the 36 minute mark) - It was at that moment when she realized that he wasn't who she thought he was. How many of us, have had those kinds of moments? I used to think to myself, did I really know him (who was I dating/in a relationship with)? Was I in love with him, or who I wanted him to be? Like dang, how could I miss the red flags!

I have one episode left. I hope that they break up, as the male lead isn't ready for a romantic relationship. He always put himself first, not once did he put anyone including God before himself, and most importantly his communication is horrible, for a romantic relationship. Yumi put him first up until the side-chick/friendship incident. In episode 13, I just found out that Yumi didn't know that the male lead liked his ex-colleague/friend. For some reason I thought that Yumi knew that, but she had to find out by overhearing two people who she didn't know speak about it. At this point, I hope her and her manager get together. He seems like he would be a better fit.

I freaking loved the ending. I can give you more reasons why the female lead and male lead shouldn't be together, as opposed to the reasons why they should. I actually don't think that this drama needs a second season. I think if it's not done right then it would ruin the credibility of the first season. Since there will be a second season, in the second season Yumi should date her manager, and the male lead should date his ex colleague/crush. Please don't have the female and male lead get together in the second season, keep that for the third season. The male lead should date someone who is just like him in the second season (meaning someone who put themselves first when in a relationship), so that he can understand what Yumi went through when dating him. Was the male lead a nice person? Overall, yes, but nice people can also be unkind. Niceness doesn't equate to kindness.

BTW, in addition to being a talented actress, the lead actress who plays Yumi is gorg.... (gorgeous).
