File:Harvest Moon Tree of Tranquility - Luna - Date

Description
When Luna reaches 4 hearts, you can talk to her before 11:00 AM on a sunny day and she will ask you to meet her at the beach for a date at 12:00 PM.

Make sure you're down the stairs by On the Hook by 12:50 PM in order to see the event. If you no-show, you will lose hearts with her.
