No.

Before marriage, what is yours is yours, and what is mine is mine.

I don’t care if you use your money to exchange for your mortgage.

As long as you are not here and you are not married, just let me raise a house with you. If you have enough money, I may give you some money myself (of course, this money is borrowed from me) The gift should be clearly agreed between the couple so as to avoid any estrangement between the two in the future) and reduce your burden. But I don't want you to ask me for money. If we separate in the future, if this part of the money was loaned to you as agreed in advance, you will pay it back. If it was agreed upon in advance as a gift, you can exchange it or not.

And you have your own house. When we get married in the future, we won’t have to worry about whether or not your name should be written in the wedding room. After all, you own your own house and have the sense of security that comes from it.

So, on the contrary, I would be happier if you had a house.

Sister, well done, I envy you for having your own cabin.
