Lin Ran has been able to see the colors of people's emotions since she was a child—the heartbroken are gray, the anxious are withered yellow, the gentle are warm yellow. She and her grandmother run an old café called The Palette, where everyone who walks in carries a color and a piece of unfinished heartache. The departure of her mother when she was seven turned Lin Ran's palms a deathly gray, until a regular customer named Lu Yuan, wrapped in pale violet, appears—and she begins to face her own colors again. A healing story set in an old café: every episode, one person healed.
