Wen Jian Yue likes staying at home.
She has an eating disorder, is sick of the world, and has prosopagnosia.
She hates it when people suddenly appear, only to suddenly leave.
She's always believed she was meant to spend her life alone.
The world is bleak and boring to her.
Until one day, an old friend moves in next door. Their repeated attempts to get close leave Wen Jian Yue at a loss.
"Su Zhanxing, love can change in an instant. If we start something, I'll have to bear the pain of us parting someday."
"I love you. I love you so much. But how long could someone like me keep you by my side?"
"Can you really tell the difference? Do you love the confident, outgoing Wen Jian Yue in your memories, or the me who isn't even human, not even a ghost?"
