I don't understand why this isn't working. Installation's pretty simply as far as mods go. BepInEx is in the game directory, the base mod and tweaks and single date are in the plugins directory, the logo on startup says "modded" as the instructions say it should. Yet the game is otherwise exactly the same as always, with no single dates.

On the title screen check the credits and make sure the single date credits entry is there. If it's not the mod wasn't found and you installed it wrong.
If it's there single dates should start appearing in the finder with girls you've already met. Introductary pairs, pairs at attracted and at their threesome-time-of-day take priority when populating the finder so If you have too many of them nothing else will show up
