Okay, so your point is that she didn't ghost him. Fine, I guess we can agree on that. However, she was still a bad friend. She didn't contact him for 17 years, didn't invite him to her wedding, didn't tell him she had given birth, and didn't even give him a heads-up that she was alive and well. For 17 years, he meant nothing to her, and she only reached out when she was having financial problems.
After all that, he still wasn't able to move on from a girl he dated for only six months? What would you call him if not a simp? A hopeless romantic? He spent 17 years putting her on a pedestal in a completely one-sided way, bordering on obsession, and couldn't move on. What else can we call him if not a simp? By definition, he is one.
And by "using insults as arguments," I meant that the guy didn't provide any counterarguments at all. Instead, he simply dismissed everyone who disagreed with him as incels. That adds nothing to the discussion and amounts to nothing more than insults.
It's never been confirmed that Kyou was married to Minori's father. He's never even been named; he's only referred to as "Minori's father", and the extent of what we know is that she met him through work, and that he died before Minori was born and wasn't put on her birth certificate/registry. We know this from chapters 16 and 19.
We also know next to nothing of what Kyou's life encompassed between the time she broke up with Takaharu, dropped out of college, and when she returned with 14yo Minori in tow. We know her parents divorced, and the aforementioned meeting of the man who would be Minori's father at "work". We
also know that Kyou was experiencing something extremely difficult that forced her to drop out in the first place. And that she's been raising Minori on her own, with no mention of help from family, and that it was ostensibly difficult for them, to the point of food insecurity.
We can infer this from multiple chapters, along with Kyou's penchant for food and how Minori herself at the start of the story remarks on how "at ease" her mother is now that she's eating regular meals and not constantly on the move trying to care for the two of them.
But, she reached out for a place to crash, as stated in chapter 1, because "their apartment was being rebuilt". It's not expanded on, but they were also in the process of looking for someplace new, and sought a temporary place to stay until they could locate new housing, and Kyou is currently employed and even offers to help with rent so as to not be completely freeloading off Takaharu (which he rejects, and instead asks she help pay food costs and assist with home upkeep).
Also, we simply have no real details on what Takaharu was doing for the 17 years between Kyou exiting his life and re-entering it. It's clear that she left a lasting mark on him, was a direct muse for his painting work even in her absence, and was important enough that he still holds feelings for her even when they only dated for three months' time. She showed back up, and his feelings for her have clearly resurfaced, but that's not indicative of him having lived in stasis and doing nothing but sitting in a room alone for 17 years hoping to hear from her again.
Reducing the complexity of his emotions for her to "being a simp" does come off reductive, especially when it's being used in what very much appears a dismissive manner to write off what he is experiencing now that Kyou's returned to his life.
Let me ask you this: are you using "simp" as a prejorative? Are you intentionally using it to insult Takaharu's character and belittle him and the arc of his narrative within the larger story between him, Kyou, and Minori? There's meaning behind the language we use to communicate ideas, and "simp" carries a rather specific, arguably charged meaning that I would argue
does oversimplify and ignore a lot of the nuance of their situation.
If you're not using it disparagingly, then I guess I would question why you would double down on it, specifically. You even offered up "hopeless romantic", which at least has some commonality with his being an artistic person.
Besides, we see that Kyou also has enduring feelings for Takaharu that have persisted in their time apart. She is also trying to quash them down as she fears they will distract her from caring for Minori, which is a major part of the plot for
her character within the larger story. Does that make her a simp as well, if she also has lingering attachments? She even sought him out, knowing he left an open promise to help her from 17 years before. What does that say about her, in your mind?
Basically - Takaharu absolutely is still hung up on Kyou. But there's complexity there, that can be discussed without reaching for disparaging slang terms that miss the layers of storytelling involved.
It reads like the person using them either possesses or only cares to possess a surface-level grasp of the story they're engaging with, and the repeated refrain of "he's a simp" chapter after chapter wears thin when it appears as though those who leave it as the sum of their contribution to the discussion threads have no interest in trying to dig a little deeper into
why he might be acting that way.
And I'll tie that into your last point: all those people calling him "simp" or "beta" aren't exactly explaining their positions or getting into why they feel that's the case or seeming to make any attempt to dig into the reasoning behind Takaharu's mindset or behavior.
It reads like a dismissal of Takaharu and adds nothing to the conversation of the story or its characters.
