As the saying goes, it's easier to borrow than to borrow, and it's not difficult to borrow again, but your brother doesn't seem to want to return it.

Don't pay it back until you pay it back. After all, you are brothers, hurting your bones.

Just remember: this kind of thing happens again and again.

Remember another famous saying: it is ok to borrow money from your brother, but you should leave written evidence in case you can't repay it. It can be recovered through legal procedures.
