Yunya

Yunya Plot:

Yunya, a convenience store clerk, has a secret—she can see "regret values" on people: unspoken confessions glow pale pink, unkept final goodbyes are dark blue numbers. She survives by helping customers fix small regrets, but recently her own "regret value" has started a countdown to zero—a warning she's about to disappear. Until Lin Shen, a mysterious man with no regret value at all, appears. He says he can save Yunya, but only if she helps him find "the girl he pushed away ten years ago." As Yunya follows Lin Shen through old photo albums and alleyways, she discovers that this "regret-free" man hides the most untouchable secret in his heart—about a girl named "Yunya"...
