Three years ago, Sichuan girl Yang Na gave up her job in Suzhou and returned to Chengdu to take care of his paralyzed boyfriend Yan Hongbo. She made an agreement with her parents that they should let them get married if he could stand up again within 3 years.
Now time is up, but the chance still looks dim. Her parents constantly reminds her of moving back home.
She fell in a dillemma. In the end, she begged her parents for a 6-month renewal of their agreement. If he won't get better in this period, she will listen to her parents and leave him.
Her boyfriend Yan Hongbo is also in a dilemma. Part of him wants her to stay, part of him wants her to persue the happiness he can't give(at the moment or forever).
