Woah this was well thought out. And makes total sense. But I thought the seme was being like bc that’s all he knows and just thinks it’s a mutually beneficial relationship. So he might think that’s how relationships with him should work. Basically make your partner happy and if money works than he gets love in return. Anyways I didn’t think it was that deep cuz he sounded like he knew what he was doing (when talking with his friend) and didn’t mind that his relationships have always been like that. I don’t think it’s healthy to expect your partner to only care about you bc of your money but I do think his outlook makes sense that helping your partner financially is pretty normal he just did it in the strangest way with a complete stranger. Which is weird. But I get that the seme liked the uke bc he could probably see himself in him and wanted to help and he wants someone who will need him. Either way I don’t think he’s toxic as of rn but i could be wrong. ╮( ̄▽ ̄)╭

This could also be a possibility. If he comes from a wealthy family, his view on relationships will reflect that. He would have grown up in a reality where money equals affection, money gains you access to people's lives and money is the driving force of life.
On the other hand, if he came from a poor family, his view on money and relationships can also be askew. If he gained a lot more friends and suddenly became "dating material" after he acquired wealth, he can be led to believe that money is the answer to all his problems.
The way he talked about couples will help each other financially as a way to persuade the uke into letting him pay for things didn't sit well with me. He was most likely talking about completely funding the uke's life, which isn't financially helping your SO. It's ownership. That's a huge red flag right there.
I think the bad feeling everyone has about the seme may be because it seems like he's trying to recreate a relationship he had in the past that either didn't work out or was a highly abusive and/or toxic codependent relationship.
We can't forget what his "friend"/writer said. The seme has a habit of getting into sticky situations and it's implied that he comes from at least an upper middle class family so we can infer, if all that info is correct, that his first and following relationships have all been people wanting to rely on him for living expenses or wanting to spend his money extravagantly.
If we make the inference that the seme was in an emotionally abusive relationship where his partner relied heavily on his wealth and possibly tried to prevent him from leaving, then the seme might be trying to recreate that part of his life. Alot of victims of emotional abuse tend to get left out on the side of the road because their wounds can't be seen. And a huge majority of them tend to become the "toxic" partner when they get in future relationships because of the lack of care and treatment and that leads them to recreate their own abuse in an attempt to understand and heal.
