Lu Xi has late-stage breast cancer and not much time left to live, but Xiao Zhendong, the man she loves, has no idea. So, to keep from burdening her boyfriend, Xiao Zhendong, Lu Xi deliberately stages a scene of infidelity in front of him, hoping to make him give up on her for good. Better a short, sharp heartbreak than a long one. Since she can no longer spend her life with him, why put him through such a devastating blow? But Xiao Zhendong doesn't know the truth. He thinks Lu Xi betrayed him, and is filled with hatred and anger. He loves her so much, so how could she do something like this...? He begins to torment and numb himself, and bars and karaoke clubs become regular haunts. Lu Xi watches, her heart breaking, but there's nothing she can do. She cries all day and grows thinner, while her remaining time grows shorter. Her close friend Si Qi can't bear to watch anymore, so she tells Xiao Zhendong the truth. He is utterly shocked when he learns what really happened, then bursts into tears, regretting how coldly he treated Lu Xi. When they meet again, they pour out their feelings and weep in each other's arms. At last, they decide to prepare for one final wedding, but halfway through the ceremony, Lu Xi collapses and never rises again...
