File:Harvest Moon Tree of Tranquility - Luke - Date Event

Description
When Luke reaches 4 hearts, you can talk to him before 11:00 AM on a sunny day (NOT Sunday) and he will ask you to meet him at the Sundae Inn for a date at 12:00 PM.

Make sure you're inside of the Sundae Inn by 12:50 PM in order to see the event. If you no-show, you will lose hearts with him.
