L ♡ S

L ♡ S is one of the constellations that can be seen in the night sky on Pine Island. And is also apparently a reference to Luke and Sandy's relationship.

Description
The constellation represents the strong relationship between the two side characters in the game, Luke and Sandy. The constellation is also apparent before the two met or were born, being present throughout the entire game's timeline (1 A.D. - 2030) instead of appearing after they met.
