>>39376911Ok, I will explain everything.
First of all, you need to learn that respect is basically everything in japan, if you don't respect others, you might as well be dead.
Then, you need to understand that in japan, dedicating your entire life to one (1) thing is also something common that the japanese people respects a lot (this is why they have so many shops and ateliers that have been passed over for several generations). And by entire life, I meant it, your work is around that 1 thing, your hobbies are around that 1 thing, everything you do, is related to this one path you chose, this is why several martial arts have "do", which means "path" in their names.
Now, you need to know what a dating ban is. It comes from junior MALE baseball leagues in japan. Where the players are not allowed to go on dates or be in a relationship because that is seen as a distraction, which is disrespectful to the other players who are dedicating their lives to it. So yes, even if you are a mega talented player that doesn't even need to train to be good, you have to do it, because not doing it is disrespectful to the others who are trying as hard as they can (this part might be hard to grasp to westeners who lives in a mostly egotistical society), and literally no one likes a person who is disrespectful to a hard worker.
And then, there was the idol culture, although most of them were adult women, young girls also started to want to become idols too, and the junior idols became a thing, which also reflected some of the culture that they had for all the young people who wanted to dedicate their lives to something that is very sought after (being on the national baseball team, or being a popular idol, of course it's also debated that the dating ban had also an ulterior motive of getting simp money, since younger girls were rarely talented enough to compete against an older singer who had much more experience and career).
After that, the vtuber culture grew around this idol culture, which adopted some of the same "rules", which includes the dating ban. This is the original motive behind it, but now, it's only seen as a scheme to get simp money, and simply for that greedy money, most of them hide their relationship status(either indie, or company enforced).
Also, this translates to the fans too. And those who dedicates their lives to a single idol, calls it his oshi (this is why it's usually the japanese that have a room with like a thousand of the same merch of the same thing). There is also another term for people who says that likes a bunch of idols, but that's usually an insult.
