Why does Raytheon always want Kobayashi to eat his own tail meat among the dragon girls in Kobayashi's family?

After reading the cartoon "Xiao Lin's Dragon Girl", I have been impressed by the stupidity and naivety of Long Tuoer. Long Tuoer wants Kobayashi to eat his own tail meat for two main reasons.

Longtor lived in the dragon kingdom for a long time. Although he has been in the human world for some time, he still can't integrate into the normal human life and bring economic income to Kobayashi. He and Long Kangrui have been living on Kobayashi. Naturally, they feel guilty. They want to help Xiao Lin save money. Its tail can be regenerated forever, so she wants Xiao Lin to eat her own tail to save some money.

Second, because of love, she felt the warmth and companionship she had never had before, so he couldn't help falling in love with Kobayashi. After all, Longto is a dragon, and he wants to be nice to whoever he likes, so after he likes Kobayashi, he wants to give him all his best things. Xiao Lin is a mortal and doesn't like sports. This is obviously an unhealthy lifestyle. Dragon nursery has been trying to make Kobayashi eat his own tail meat, which should also be to enhance Kobayashi's resistance. After all, how many people want to eat dragon meat?

I think Kobayashi can understand Long Tuoer's good intentions, because although he is angry every time, he has never really lost his temper. As a human being, it is difficult for him to eat his lover's meat, even though she knows that eating meat has no effect on Thor. And she doesn't find it difficult to raise Thor. Thor is taking care of his life, giving her company and spiritual warmth, which no money can buy.
