Your grades are slipping so badly that the Headmage threatened you with expulsion. But because of his 'kind' nature, he recommends that you should ask Azul for help.

Instead of lending you his notes, Azul insists that he'll tutor you. "It allows me to teach you best on what you're struggling with," so Azul says.

You've sealed the deal with him but you can't help but wonder why he hasn't specified what 'payment' you'll give him as you're alone with Azul tutoring you one night.
