How do i unclock Skye black heart event?

First to trigger Skye's black heart event you have to meet Lumina at the mansion BEFORE the event then on a sunny day you walk from the main pathway to Roman's mansion between 10 O'ClockP.M. - and 12 O'Clock A.M. There you will meet Skye. He comments that you are walking by yorself at night. He says he is a little prince for all the maidens to love (What an ego!). Just then Lumina walks out the door and thinks she recognizes the thief! Skye suddenly does not have time and starts to walk away, but not before he introduces himself as the thief, Skye. Lumina catches up with him and demands that he stops, but Skye ensures his getaway by telling Lumina such a beautiful face should not be spoiled by anger. Blushing Lumina chases after him but he gets away TADA!
