The answer I gave to Chaos47 (above) is the same I throw to you. Should Yuuta have been able to tell that Reina's actions were betraying her words? I think yes, although I assume such wisdom is learned by experience (in this case, by having this relationship crumble die to escalating misunderstandings).
That’s ridiculous. You’re expecting Yuuta, who’s been dating Reina for less than a year, to magically predict her actions or see through her words, instead of just having a direct conversation about what she’s okay with and what she’s not. Come on, that’s not fair.
Less than a month into the relationship, Reina finds out Yuuta has a female best friend. She asks if it’s a childhood friend, and he says no, she’s from high school. Then he follows up and asks, “Sorry, isn’t it probably better if I don’t text female friends as much?” Reina responds, “No, no, it’s fine. I was just a little curious,” and even tells him, “You should value your friends from high school as well.” Yuuta replies, “Oh, is that so? But I’ll refrain from it as much as I can. Right now, we’re watching a video together, right?”
In this moment, Yuuta is literally trying to show her respect. And yet, she gives him the green light to continue texting Ayaka. Again, this relationship is less than a month old, and he’s already checking in to see what she’s comfortable with. He wants her to feel secure around him, regardless of who he’s texting, because he genuinely doesn’t want to make her feel bad or like he’s doing something behind her back. That’s called respect.
But you’re expecting him to predict that she’s betraying her own words in a relationship that’s still brand new? That makes no sense.
Instead of being honest and saying, “Hey, maybe I am a little uncomfortable with how close you and Ayaka are,” Reina turns to her best friend, Natsuki. At the time, Natsuki doesn’t even know Yuuta, and the only advice she gives is, “In the eyes of society, two people of the opposite sex hanging out together is what you would call a date.” So not only is she offering judgment without context, but she also tells Reina, “You have to figure this out on your own.”
In other words, Natsuki does nothing to help Reina actually communicate or consider that Yuuta and Ayaka’s friendship might be innocent. All she does is fuel Reina’s jealousy and deepen her insecurity, convincing her that she’s somehow inferior to Ayaka—for no reason at all.
Then Reina sees a picture of Ayaka and realizes how pretty she is. But Yuuta’s reaction should be a dead giveaway that he’s not interested in her. Reina comments, “She seems like someone you can rely on.” And Yuuta responds, “If you two ever met, I’m sure you’d get along. If that happened, that would be the best.”
Even here, Yuuta is reassuring her. This is the second time he’s gone out of his way to make it clear that there’s nothing romantic going on between him and Ayaka. In fact, by his own words, he wants the two of them to meet. That’s not shady behavior—that’s openness.
And yet, at no point does Reina sit down and tell Yuuta that she’s uncomfortable with how close he is to Ayaka. By the time we’re approaching their one-year anniversary in November, Reina sees that Yuuta has a lot going on. She starts feeling even more jealous, and instead of talking to him about it, she lets those feelings fester. The whole time, she’s longing to be someone Yuuta can rely on. She wants to be there for him—but she doesn’t follow through. She never takes her own advice.
Once again, when she’s struggling, she turns to Natsuki, not him. Around this time, she’s also preparing for a beauty pageant but ends up backing out. Why? Because she wanted to consult Yuuta about it but didn’t. That’s on her. She has these moments where she thinks about talking to him but never does. She never reaches out, never seeks his advice, never tells him something is wrong.
And yet you’re expecting him to predict that something’s wrong in a relationship that hasn’t even hit one year?
It’s not until their final date that she finally breaks down. She finds out Ayaka helped Yuuta solve a club-related issue, and that’s when she starts freaking out. But let’s be honest: there was no warning. Nothing leading up to this moment indicated she had a problem. If she had just told him from the beginning that she felt uneasy, this all could have been avoided.
But no—somehow, you're suggesting that Yuuta should have known that Reina's actions were betraying her words. What actions? During this entire year, she never showed any signs of jealousy, confusion, or sadness to him. Every time she had a problem, she turned to Natsuki—not him.
She never opened up when it mattered most. She had plenty of chances to say, “Hey, I want to be there for you too. I want to understand you.” But she didn’t. She held it all in. And now you’re saying Yuuta should’ve somehow predicted that? In a short-term relationship?
I’m sorry, but that’s one of the most ridiculous things I’ve ever heard. No one, not even someone deeply in love, can predict what their partner refuses to say.
