I've been playing for quite a while, and am on nvln19.1;. When I knock on Autumn's door and pick TALK, I get a message that says *Lin's* relationship isn't high enough.
Thanks! Another question, On the stats screen, some girls have a big yellow exclamation mark next to their name (in the overview). What does this mean?
Make sure you have a save in your manager's room before doing that last Lin quest, though. At least until the game is finished. You'll see why once you do the quest if you haven't by now.
