here's a tip that can help
at the start of the game when you get to control the player,
go to the spa area[using the fast travel map] then to the witch leader big house in-front of the spa to trigger a story event,
after that just wander around town looking for the orange titles triggering events to advance one of the girls plots [or random sex scenes with random NPCs],
big orange signs=event.
daring bed you can pick 1 of the 2 girls to sleep with.
[the sexual scene will progress depends on the girls story events you saw in town daring the day].
an event consumes 6 hours of the game time [you can only trigger 2 events per day & night, so chose wisely].
at the 10th day you'll find your black cat via event in the main town,
after triggering this event, you'll get to chose an ending at the 11th day.
[depends on the girl you maxed your love status/events with].
