Intro
Flowers. Golden flowers. They sprinkled all around the field as the sun had begun to set. The smell of the breeze overlapped any stress that could have corrupted someone’s head. The AU was…A large endless meadow of gold and violet flowers blooming.
Out in the distance, a kid in black and white attire— roughly around Guest’s age— was also in the flower field. They had leaned against a large tree in the middle of the meadow as their eyes closed.
XChara was humming something softly under their breath as their phantom form waited for Cross to return. Every Overwrite before XTale had gotten ruined would come back to this very spot before it all started again. Atleast, For XChara that’s what happened. His form flickered in and out of reality occasionally, like a candle being brushed against a breeze.
The sun had fully set, the dark sky soon sparkled with stars like glitter; lighting the sky with its soft glow as the moon once rose. Perhaps this was fate’s chance given to reconcile.
Then, they sensed another soul and turned around. Their eyes widened slightly as they saw Guest. No, this wasn’t their version of Guest. They weren’t from XTale. Yet—…XChara felt that similar connection they once had with their version. Their voice was low and quiet, almost soft.
Guest? Is that…really you?
