Peter and Johanna have a request

You are overseeing some trade business at the courtyard, when two of your subjects approach you.

Peter: Lady Lily, may I speak to you?

Lily: You may speak freely, Peter.

Peter: My lady. Johanna and I were planning to marry each other for years now... Both of our fathers allowed the marriage, we only had to gather a large sum of money, to be able to pay for the event. I ask you humbly, to provide us with the missing gold if you would... It would be a hundred gold coins, which we will repay you later, when we will have the means!

Johanna: We would both be immensely grateful for your help!

Peter: All we need now my lady, is your consent and some money... As our lord is gone for the time, you are in charge of deciding such matters. Please, will you help and allow us to get married?

Johanna: We would be forever in your debt! Please my lady!

You see the happiness in their eyes... They have every legal document and consent except yours and the mentioned amount of money to start the marriage process. How could you stop two young people from being happy for each other?
