Lin Chi suffers from a rare "emotional exhaustion syndrome" in which he will gradually lose all feelings and eventually become an empty shell.
The only antidote is to exchange one's complete love memory.
Her lover Jiang Du happens to be the perfumer of the Emotional Pawn Shop.
He re-injected the memory that had been mortgaged seven years ago into his body, fell in love with her again, and personally extracted this love into an antidote.
Lin Chi recovered.
Jiang Du forgot about her.
"I knew the story, but I couldn't feel it," he said.
Lin Chi said: "It doesn't matter. I'll remember it for you."
