ROFL, Shiori is really a troublemaker haha. Anyway, to fix the other thing you spotted, I'm going to stop the romance at that point too (I think is the only way without messing other stuff). So that on Day 5 if you don't trigger the Shiori indecent proposal that route is blocked.
Strange since when you break romance the relationship should go down. Maybe that doesn't happen and it's the reason. Going to check
