I'm just calling back to 13.5 when Aya says there's 0.01% chance Yuu isn't referring to Hikari
That 0.01%, in any case, must refer to the possibility that Yuu was in love with someone other than Hikari or Yami. Yuu spoke of "someone I've been in love with for a long time", which obviously doesn't apply to Yami, who was only Yuu's girlfriend for six months, and in any case, it's only in chapter 13.5 that the first anniversary of their first time together had come.
You are welcome to disagree w/ me, but it is reasonable to interpret the following text as Aya was planning to ghost. Where that goodbye is referring to this goodbye
I still find your interpretation too much forced, especially after looking at your timeline. It doesn't make sense that Yami would lie, not only to Yuu, but also to the reader in her inner monologue, about something as important as her mother's suicide, and then go so quickly from proposing they live together in chapter 28 to wanting to break up in chapter 29. That's why it doesn't make sense for her to insist to everyone that everything will be alright at home, that her mother is fine, that everything is sorted out, while her mother is literally recovering in a clinic after a suicide attempt. That would be too much of a lie, even for Yami.
And I don't think for a second that Maruto intended to portray her as such an unreliable narrator in such an exaggerated way, including the line where she tries to convince Yuu to stay longer at the hotel and he says his parents won't let him (Why do this if she already had to beg for an extension for only 3 days?).
Of course, another issue is that for your theories, which lack significant textual support, it's necessary for Yami to be this much of a liar, not only with Yuu and Hikari, but also with herself and the readers who see her thoughts.
That's why I consider it most likely that her mother's suicide attempt occurred during that three-day trip, and Yami finds out in a phone call that conveniently happens during one of the many periods when, according to her, Yuu was asleep while she stayed awake.
Therefore, I believe that "this is what I decided from the beginning" refers to her "carefree girl living in the moment" attitude, which is indeed a lie.
That's the difference between her "I love you, Yuu" in chapter 27 and her "I want to be with you always, Yuu" in chapter 28. In the first example, her internal thoughts make it clear that she's avoiding her family conflict. In the second one, her inner thoughts confirm that here she is 100% honest.
Even expies don't mean identical. CLAMP's multiverse is literally shared soul and CCS Sakura & Syaroan are still different from TRC Sakura & Syaroan
I never said that the Expies meant identical. Obviously, Yuu Izumi and Yuu Takamura are different characters, just as Sakura and Shaoran from CCS are different from Sakura and Shaoran from TRC, or Takeru and Sumika from Muv-Luv Extra are different from Takeru and Sumika from Muv-Luv Alternative, since they've lived different lives and had different experiences.
That doesn't change the fact that they share a soul, as you said, a common basic personality, just like Ayami Sudo and Ai Kamiya; and that all the hints we've seen of Yuu Takamura on screen show him as someone who, as far as we know, doesn't seem like the type of person who would be capable of lying to his parents under pressure. I gave several narrative examples that demonstrate with evidence that this is indeed a shared trait between Izumi and Takamura. Definitely, as I said, I can see him giving his parents what you called "the PG version" of his relationship with Yami as soon as they pressured him about it. If his parents could keep his exam a secret, they could also keep his relationship with Yami a secret.
That's why I say the burden of proof is on you to show that Yuu would be capable of lying to his parents and completely avoiding the issue under direct and sustained pressure. Nothing about him suggests that.
She attempted suicide before the whole trip.
I've already explained why I find it too unbelievable and inconsistent with Yami's portrayal in chapter 28 that she, in this moment, already knows her mother attempted suicide. It makes much more sense that the news arrived via a phone call during the mini time skip between chapters 28 and 29, and it would be more appropriate for Maruto's typical melodramatic tone.
The people I know who are sad and depressed because of a failure don't usually go partying right after it. And we saw what Yuu was like after it, so he is very unlikely to be that type.
I mean, many people certainly do go out partying to try to forget a failure. Even if Yuu doesn't seem like that kind of person, it's also clear that this is the first time he's failed so drastically in life, affecting him so deeply, which explains why he made decisions he'd never made before.
If he used "hanging out with friends" as a pretext for his outings, I don't see why it would sound too forced if in of those outings his hypothetical friend hypothetically got injured.
What exact word does he use for "my friend" in the call in chapter 26.6? Does it have a gender? Is he referring to a male friend or female friend? It doesn't help that the Japanese
"kanojo" is closer to
"novia" in Spanish than
"girlfriend" in English.
Anyway, if he doesn't give details about his friend's supposed injury, it feels like a very forced excuse (at least compared with the party in Kaneda house, over all seeing the respective contexts), especially since if they're just hanging out in the city, it would be very strange for someone like that to suddenly need to go to a clinic.
In what way? Even on the day of exam results announcement he is the one who calls them late at night (from the hotel), not the other way round. They aren't even too worried by not hearing from him even though it's nighttime already.
We don't know to what extent he texted his parents during the hours he spent on his date with Ayami at the restaurant, which is why he says he'll stay in touch with his mother in the hours that follow in chapter 26.6—that is, he's afraid his mother will call him if he stops communicating.
In any case, according to chapter 24, it was still relatively early in the "nighttime" when they entered the love hotel, probably around 9:00 or 10:00 PM.
The flirtatious senpai is the lie
Yes, that's exactly where your entire argument falls apart. You're making up, without any textual basis, that Yami is lying about playing the role of a flirty and dominant senpai when it's literally the most basic fact of Ayami Sudo's characterization, even in the Hikari arc —remember which chapter is "Aya-chan's" debut?
Ayami is a girl who likes to dominate, likes to give orders, likes to be on top, likes to take the initiative. Her main sexual trigger is that she likes to see Yuu trembling and writhing. In short, Ayami does like
being the boyfriend in this relationship.
The fact that she also has a more tender and sensitive side that Yuu did see and tried to reach doesn't mean that the flirty and dominant senpai side is false (what is a lie, in any case, is the mask of a "carefree girl who lives in the moment", something different, and something Yuu does directly call a lie). And yes, as I said, Yuu Takamura did make the effort to take the initiative at times and respond emotionally to Yami, typical of these female domination mangas. That's why it took external problems to sink the relationship and the strong emotional connection they had.
Chapters 24, 25, 25.5, and Omake 4 made it clear that Yami can be, and wants to be, dominant without needing to lie or wear a mask. And yes, part of that dominant personality stems from the fact that this is the only way she can be involved in a romantic relationship, being in control and knowing with complete certainty that Yuu won't do anything she doesn't want.
You're precisely repeating Yuu's fears from omake 4 after the breakup, when in fact, Yami's POV in chapter 13.5 —and repeated in chapter 39— makes it clear that that emotional connection was real and that she truly loved and still loves Yuu precisely because of his submissive and innocent personality.
That's why, even without the trauma of the attempted SA, she was already compatible with Yuu, based on what Yuzuka implied about Ayami's past. This dominant girlfriend - submissive boyfriend dynamic is what allows them to function as a couple, and as I said, it's something copied from Yuu Izumi and Ai Kamiya from Shikimori-san, the characters on whom Yuu Takamura and Ayami Sudo are based.
Her annoyance with Yuu, in any case, is that he didn't grovel after her as much as Hikari did, nor was he as masochistic as Hikari.
