Ok first of all.. this is the best way to get started. Ignore all girl events until you need them and how to determine that.
1. Start with Main Events Tracker Chapter 1
2. Check the further progress you are in on that Tracker
3. Click on the Guide/Wiki > go to
You must be registered to see the links
4. Go to the events and start at the 0.1.0 and go through them in order
Ok a good example let's say you have not done all the way to 0.3.0 events and you are now needing to do Girl Talk.
1. Click on Girl Talk
2. You will notice there is 2 requirements for this event to trigger: Seen: Carry Me Home ; Seen: Nothing Was Missing
3. Click on Carry Me Home and you will see that is a Sana Event requiring 15 affection and will trigger at the bar
4. Click on Nothing Was Missing, Except Me and you will see that is a Rin requiring affection 20 and requires the Missing Event
If you progress this way you will trigger what you need and will also see events that you need to trigger to get that event. So just follow the requirements in this method and ignore girl events you will get the girl events as you trigger what you require for the main story events. It took me a bit of a while to figure out this method as I was doing main girls than side girls and you will not get these main story events to properly trigger and you will remain stuck. I did not realize the guide and how it worked and I am on day 9xx something because of this.
