If you really want to know, you can ask the master. If the master wants to keep you, he will certainly keep you. If he doesn't want to keep you, he will find time to tell you instead of asking him.

Don't doubt yourself if you don't have the courage to ask. As long as the master doesn't talk, it means that you can learn and have certain development potential. Everyone should have a learning process when facing a new job. The master will understand.
