The ex-wife wins him back, a sweet and angsty one-on-one romance, a wolfish older man and a puppy-like sweetheart versus a healing little ray of sunshine, two hurting souls saving each other.
A virus breaks out, wiping people's memories of the person they love most every seven days. Lin Zhi discovers that everyone in her contacts is growing blurry, except Shen Du, her scummy ex-boyfriend, who tricked her into signing a “love experiment consent form” two years ago. He stands out with painful clarity. She thought he didn't love her, so of course he wouldn't forget her. But when she finds him, he no longer remembers her. That's all right: she's holding the experiment contract he wrote with his own hand. This time, Professor Shen, it's your turn to be played by me. Every seven days, you forget me once, and I beat you once. The wager is this: seven days from now, will you keep forgetting me?
It's beautiful, come and take a look
