Legal analysis: I asked you to sign it for me and promised that you didn't care about the loan. You just need to sign for me, or even issue a written agreement, indicating that all the responsibilities have nothing to do with you. However, when the borrower's relatives can't repay the loan, you still need to bear the responsibility of repaying the loan.
