Frankly if your players don't care that you've already decided what they're going to do then they're shitty secondaries who are just there to socialize and belong to a group. They don't deserve a good DM or game.
You (a shitty secondary also) who's just there to socialize and tell your gay little story you're too afraid or incompetent to just write and self publish with all the AI slop on Amazon Reads, deserve no better as well.
Thank Crom you're all clumped together having a bad game to yourselves.
