How do I get the lunch date heart event with Gill in Harvest Moon Tree of Tranquillity?
You should still be able to do it if he has 5 hearts. With any of the bachelors, to get the lunch date, you must talk to them between 10 and 11 in the morning. Then you need to go to the inn for lunch between 12 and 1. However, it doesn’t work if you have already talked to your date before 10. The same is true for the love confession later on.
