Synopsis

Aria was just another overworked office drone until she got a terminal diagnosis. Desperate to live, she found herself thrown into another world with one mission: win Greyson's love until it reaches 100%. She played the part, married him, and ended up actually falling for him too. He spoiled her and cherished her. But that last bit of love never clicked. Then she caught him cheating. Devastated, she gave up and bounced back to her old life. Only after she ""died"" did Greyson realize what he'd lost. Blinded by regret, he crossed worlds to find her and ended up giving his life so she could have a happy ending with someone else. His final act paid the price for his betrayal.
