When the rain fell on Wutong Lane, she met him - a face that was exactly the same as that of her lover who had been missing for three years.
He is Lu Chengyu, a gentle and elegant architect who breaks into her closed world with just the right amount of tenderness.
She is Su Nian, guarding a flower shop, and also guarding a vague wait.
"I'm not him," he said.
"I know," she said.
But when he handed her her favorite roasted chestnuts, when he held an umbrella for her on a rainy night, when his fingertips inadvertently brushed the ends of her hair -
She still couldn't help but indulge.
Until a ring stained with dust and a blurry surveillance video brought clues about her missing lover back to her life.
Who is he?
Why did he come?
And what secrets does the mysterious man who walks with his lover in the abandoned factory hide?
When the substitute's tenderness becomes a habit, and when the shadow of old love never dissipates, how should Su Nian make a choice?
An encounter that started with a similar appearance will eventually reveal the obsession and truth that spanned three years.
"Are you the old shadow that I can't get rid of, or the new light that I am destined for?"
