I wish I could demonstrate with a picture or two. You would understand immediately. But it's not possible here.

The way she reacted, she proved him right.

And it did.

I am talking about how she asked him whether he was swayed. That one he answered immediately with the truth, without hesitation, because he believed in their relationship being solid (wrongly). Don't you remember how the cells were debating, and then there was this writing under the question, saying it's a question with a time limit of 0.1 second? While the cells were debating, he had already answered.

She is insecure, immature and over-impulsive, she always tries to hide her true feelings and lives for the image she projects on other people.
One example is how she handled Woong.
Remember her lies at the resort, because she was ashamed of reserving the room with the clear-walled bathroom? She made such a fool of herself, and then was ready to go home ruining the whole vacation.
Remember her lies at that wedding? That she's supposedly going to have a wedding with Woong in Hawaii next spring?
And how she was ashamed of his style and dreaded how he would look in front of her friends?
Of course Woong was at fault for putting his pride first, no doubt about that, and that was the main reason for their breakup. But did she talk to him, did she fight for their relationship? She basically said "Oh, yes, that's a good idea, I was also thinking that" (not word by word, just the sense), to protect her own pride and not to seem like a loser.
One would think that after all that she would have evolved and matured. But this season proves the opposite.
She left her job on impulse, without thinking that a writer doesn't start making money until quite a long time, and her savings would probably not be enough.
The moment a contract is announced (not even signed! And anything can happen, remember the job offer to go back to Daehan noodles, that was taken back without warning?) she invites her friends and treats them to dinner in an expensive restaurant, spending almost all her remaining money.
Not only that, but that was the long-awaited reunion with her boyfriend after a long time (we aren't told how long). It was to be a romantic getaway, but she invites two other people. What???
A more recent example, the cake scene. A confident person would have laughed and said to Control Z: "Hey, you were right, this ginger pie sucks. Let me order something else". And they would both have laughed it off. Instead she had to gulp it down and do all this theatre, which of course didn't convince anybody, just because she didn't want to "lose face". Like a 12-year old.
When, in Jeju, she has the discussion with the young woman, she immediately takes her bags and leaves, without answering her phone, making him search here and there on the island. She doesn't even bother having a conversation with her boyfriend, to give him a chance to tell his side of things. Doesn't he deserve as much, after one year of his having shown a really good character, supportive and warm towards her? AAAAND... She had bragged to Control Z about how honest her relationship is, but then when her boyfriend is completely honest (anybody else would have told a small lie on being swayed) she rewards him ... by dumping him.
And you're asking what's annoying about her? She still has a lot to go towards maturity, if it ever comes within the next four episodes.

But we saw her in a picture, getting married - although the groom's face wasn't shown, it was definitely a wedding picture.

The part about being swayed or not was the defining part, not the why he moved house. That part he could well have concealed. He replied quickly with the truth.

Frankly for most of the series I've been annoyed at Yumi more than anyone else.

She does make wild decisions. Such as leaving her job before having anything sure in her hands. Such as leaving her boyfriend based on something someone else said, without even talking to him first or giving him the opportunity to explain himself. I mean, after a year of relationship, didn't he at least deserve that much?
I'm saying that Yumi acts on impulse, and it's not the first time either.

So he was penalized for being honest.

Is she that perfect that she needs a perfect man? Who is perfect in this world?

Can you imagine Yumi's reaction if Babi told her about the confession? No, just imagine. And them being thousands of miles apart.

Very well said, my feelings exactly.

Yes, some people just don't want to make the effort for a relationship. Quitting cowardly is much easier. It does hurt, but it's easier.

See, when he did tell the real truth, honestly, he was punished for it. Because Yumi doesn't have the maturity to handle it.

He did answer. We weren't shown it, because they were showing the cells' village at the time, but they said "he already gave the wrong answer"

She boasted to Control Z that she has a 100% honest relationship, but then she showed that she can't handle honesty, and frankly Babi was punished for being honest. Now he must be thinking "I had better tell her a lie, she wouldn't have broken up with me then". And next time, he will remember this, and tell lies to his girlfriend. She ruined a sincere person.

Exactly. You know, I think that the ones who are "all or nothing" are young viewers. I would have been like Yumi myself when I was a teenager or in my twenties. When you mature, you understand that nobody is perfect, and no relationship is perfect. We also could feel a moment's attraction for someone else, but if we don't act on it, it remains just that, a momentary thing, whereas our priority, our soulmate and life partner remains the one we committed to. A strong relationship doesn't fear such little bumps. But most of the viewers are not mature. And Yumi surely isn't. I mean, her Love cell started by thinking about it rationally, but wasn't able to keep the rage in.

However, he made his choice. He decided his priority is Yumi, that's the woman for him.

Or, let's say, it was somewhat wrong, but still, who is 100% perfect? The important thing is the way he dealt with the problem.
