I finally started this and ended up doing a mini binge of it. I like it alot and agree it is fun to see a couple actually in a relationship. While I love the scenes with the cells I do think that they have taken a little bit away from me feeling as invested in our OTP as I'd usually be. It just seemed like they were all of a sudden in a relationship with most of it shown through the cells.
I love that Yumi handled the bathroom incident with such grace and never did anything that would make the other person feel more embarrassed or uncomfortable.
Even though I know as the viewer that Sae-yi is a toxic character I didn't like that Yumi went in with a plan to stake a claim at Woong's work place and for the benefit of his female Co worker. Though the tea finally had me purchase a similar type. I've seen these types of teas before and finally had to after seeing how good it looked with the sparkling water.
I like how the show explores how moods and situations can change so quickly even against our own wants. Like how quickly suspicion took root or the fall out from the room.
I'm really curious as to who Minho's character has a crush on? I wonder if it is Yumi's supervisor.

Missvictrix, that was the first thought I had this week while watching--that this is a true slice-of-life. More than any other kdrama slice-of-life I watched. We get all the details, all the small problems. And although I didn't read the webtoon, it feels like a slice-of-life romance webtoon/manga with how episodic it feels, each episode tackling one small obstacle in their simple relationship.

In another drama, eps 5 would probably already drive me up the wall with all those Sae-yi-related-frustration. But the cells made everything not just bearable, but also interesting even when we were presented with the same old sequence of insidious little comments from annoying second lead, subsequent jealousy and exploding emotions at the most inopportune moment, and the close call with premature breakup (thank goodness for Love and Rationality).

I really like the way they portrayed doubt as this very insidious gas that poisoned everything in Yumi's heart. Seriously, the cells village in this drama has the most accurate and relatable representation of the complicated process inside people's mind and heart. The self-edited explanation from Woong, the hand-dryer of bullshit repeller, the birthday gift wheel-of-fortune. It's all those little things that made it easier to withstand Sae-yi's intentionally ambiguous but deeply hurtful words and actions. The way she hides behind her oh-so-innocent facade of helpful best friend is just UGH. I'll take Ruby and her annoying aegyo over her any day.

It shouldn't surprised me that this drama knows how to alternate its tone between the two eps each week. Just like the hilarious almost-disaster in eps 6 and its steamy conclusion compared to the more sombre previous eps. And yet both has its touch of realism, exploring all the up and down and utter unpredictability of a relationship. How the weirdest timing or even the most innocuous comment could trigger an avalanche of change in their bond and understanding of each other. Also, it's been quite some time a drama managed to handle and engineer the most real (and utterly uncomfortable) secondhand embarrassment with aplomb like this.

I'm just loving this, although I can't point to exactly what it is that I love so much in this drama. It might just be that the two leads are so adorably normal, and that there's something sort of inspired about the way we encounter their inner feelings through those cells. Also, it's nice to see a show dwell on all the usual beats of a new relationship: the giddy happiness, but also the uncertainty, the self-doubt, etc.

I'm also impressed with the amount of thought that went into each of the two leads' cell scapes. In Yumi's case, the cells talk constantly, bouncing thoughts off each other, trying to build consensus, because she's a frustrated romance novelist. In Woong's case, on the other hand, the leader cell is clearly in charge and everything is run through a properly organized process and command center, because Woong is an engineer and that's how his brain works.

I also appreciate how the drama highlights the things we sort of suspect, like how men forget to tell you things because they're clueless and not because they have the nefarious intent that overthinking women like Yumi (and me, lol) believe they have.

This is turning into one of my favorites. Though I was cringing and almost covering my face during the toilet scene and the hotel scene where they replayed Yumi’s phone call. Serious second-hand embarrassment!

The writing is pretty amazing here in terms of psychology. In these episodes, the portrayal of Woong’s lengthy thoughts, followed by almost no words of explanation coming out of his mouth, was hilarious (and infuriating!) for its accuracy. And the fight on the trip was super well executed to show how we contribute to things going wrong for ourselves even (or especially) when we want them to go right.
The animation in these parts adds a lot to the story because we see the cells fighting it out with each other (these characters have choices about how to respond). Without the cells, we would be judging the characters’ personality types (based only on their actions). Instead, we get a larger story about how people think, feel, make decisions, and then act—and all the complexities that go into our behaviors and responses.

I really liked to see new cells in each episode like Etiquette, Sullen King or how some emotion acts like doubt.

I find sad that Yumi has an active life only when she's dating. Travel Cell died because she wasn't dating and didn't travel anymore. It doesn't sound really healty.

Sae-Yi is a snake! I'm happy that Woong sees her trueself.

Was anyone else expecting Travel Cell to come back? Perhaps clawing his way out from under the tombstone like something undead?

Women like Sae-Yi are the reason why female friends to boys always have a bad rep. I have zero problems with m-f friendships, I too have many friends, close ones at that, who are boys. The key to navigating future girlfriends is to stick to your lane. I AM the friend. SHE IS the girlfriend. I wish people knew their place. Also, what's with Sae-Yi selfishly stringing along Woong like a back-up plan? :/ :/ Glad Woong gets his bear-mode up dealing with her.

I really enjoyed the poop episode and how Yumi handled everything. My only complaint is that I wish she made Woong change out of his clothes after unclogging the toilet, and before getting onto her clean bedsheets. T_T

As relatable as I find Yumi and her adorable cells, I wish she wouldn't lash out so frequently, and self-sabotage her happiness. She's someone who doesn't see the bigger picture & internalizes most of it, but I hope she grows out of such tendencies :)

Also, I never thought I would find, gigantic-hands, broad-shouldered Ahn Bo Hyun adorable in a character, but here we are with Woong. The man has really beautifully expressive uWu eyes! <3
Also, what a waste of that glass-walled shower!!!!!??? :P :P :P

Yup this is definitely a slice of life romance. And i get why these are very rare in dramaland. Without the cells, the story of the leads may be too simple to keep the audience hooked. But honestly I would still watch that, it's much better than adding suspense, makjand, crime etc to romance for dramatic purpose.

When Yumi's reason cell went crazy and so did the ecpressions of KGE, that was some amazing acting. She's perfect for this role.

Though the cells for me are not that of an adult because they look so much like Doremon or Boss Baby. When the Sulking cell came and only did "peung" LOL that's sth a baby would do, too cute. So it's actually harder for me to think that they don't belong to a child but nonetheless this was one of the most hilarious episode I've watched in a long time. We got not one but two incidences of second hand embarrassment to keep the stakes equal in the relationship.

Thank you for the weecap @missvictrix!

Though our couple is very much into each other, I liked how this week's episodes focused on the hurdles they still need to overcome.

I liked how Episode 6 showed both Woong and Yumi hiding and bluffing their way through embarrassing situations--only for it all to backfire on them the harder they tried. As they're still in the early stage of their relationship, it makes sense that they're overly worried about maintaining a perfect image to each other.

I'm glad it all resolved by the end, with the two of them closer than before!

i am loving this drama.. lust cell is a hoot! (esp, when she is picturing our ML naked, thank you drama gods) But that final scene was* chefs kiss* that aside i agree the animation takes what could be a mundane story of a couples journey in to something special. we get to actually see the thought process behind the actions. Also our leads are just to cute

Woong is my favorite character of this drama. I know Yumi is the lead and the focus, but for me, Woong and his cells takes center stage. He can be a little slow, but once he is aware of a situation, he tries to fix it or provide Yumi with a sense of security and comfort. He is just truly open and genuine in his affection and has no interest in playing relationship games (which I find wonderful and refreshing).

Snake Yi (thanks @lordcobol) is really getting on my nerves. She is completely selfish. If she wanted to date Woong she has had every opportunity to do, do not use him and your backup plan. To sabotage his relationship on the dl is despicable. I cheered when Woong let her know he was onto her shenanigans. Maybe now she'll stop but when I think about it...nah, she won't. It'll take Woong to really confront her for her to give up on him.

The cells continue to be adorable and fun. This will probably get all (even though there won't be many) of my beans at the end of the year. I watched this for Kim Go Eun but Ahn Bo Hyun has been great in this role. This is practically perfect casting.

Although I love the OTP I didn't enjoy so much screen time devoted to the cells. I almost ditched this drama after the season premiere because I don't care for animation. I have since changed my mind.

I still would prefer to see more OTP and less cells but I can see how friendless Yumi needs the cells to let us in on what her thought process is. At this time I don't miss her interaction with anybody else since that conversation would be redundant.

I love how Yumi was totally honest with Woong when he knew she was angry on the cell phone. I also respect Woong for his insight on Sae-Yi and not falling for her games. We need more communication like this which sadly is lacking in most Kdramas. Kudos to Yumi's Cells for creating a healthy, realistic atmosphere where romance can blossom.

Just musing but it occurs to me all of the “female” cells are old school stereotypically feminine in Fashion,Love, sensitive, etiquette, anxiety while Reason, Naughty, Detective ,Medic Etc are male. Woong apparently has no “girl” cells.

I started this last night and binged up to here. I found it really difficult to get into but am now loving it. Everyone else has said so much about the delights of the cells with their different personalities and the layers of understanding that they add to decisions and misunderstandings in a relationship. I particularly love the differences between the two cell villages, although as already pointed out the gender differences are a bit stereotypical. I've mostly been enticed by the humour: the naughty cell, the colon cell, the hunger cell - those most basic cells that drive us. The idea of the animation put me off until I started to see it in action. It's fun and funny and a novel way of illuminating relationships with all their ups and downs.

I adore this drama to pieces. Just started it yesterday and it was so so good. I like how this drama makes you relate to the main characters. So many times you never know what's going on in people's minds, but these expressive cells really help to get insights into their inner worlds.

Sae-yi is horrible (so catty and territorial), but a necessary hurdle to cross if Woong and Yumi are going to have a happy, stable relationship. I was surprised we got to see her cells and message board too though, I had assumed that was for the main characters!
