actually its not easy to get dad’s event, benoit just got REALLY lucky, because that event’s time frame (of availability) is very short, and you have to be rank S first and hit the right time to trigger the event; it’s more or less luck, but if you really want the event, try this:
- get to rank S as soon as possible, even if it means completing missions you dont want to (and risk girls hating you at the end), but it’s up to you to weigh that.
- the event happens after cobden opens the jar and gets possessed. after that, and when you get your S rank, dont take on any missions, keep staying in the inn to pass time and talk to jim every time you stayed at the inn and hopefully you will trigger the event
of course, you should backup your progress first beforehand in case you can’t get dad’s event, and all that time is lost when you can do other missions otherwise.
