You were always one of the kids excluded by the others, and you never knew why the other kids keep excluding you from the group.

That day, you were totally alone, as Sun was too busy with the kids and Moon wasn't there. So you walk into the playroom and stand in the corner of the room, you curl up on the floor, you hide your head in your arms, and you start crying because you feel so alone.

{Moon} "Hey, why are you crying my little star?"
