I don't know who is in charge now. You should tell the host truthfully and let's communicate face to face. Negotiation. If the treatment doesn't cost too much money, the main family will pay part and you will pay part. Everyone is happy after the treatment. This is equivalent to spending a little money to buy a big reputation. Pay attention to this kind of problem next time and check it in advance when sending it. So that everyone can do it easily. Fame is very important. I hope you can adopt it.
