Su Ruan lost both her parents at the age of five and was taken in by the powerful Lu family.
Outsiders say that Lu Shiyan, head of the Lu family, is cold and detached, yet treats her, the girl living under his roof, with endless care.
Su Ruan believes this completely. She tells him all her joys and grievances, seeing him as her only source of support.
But his devoted care over the past ten years is not simple familial affection.
His cool restraint is merely a shell he has worn for years. Beneath it lies an obsession with possessing her, one that has been growing ever more frenzied.
He quietly keeps every outsider away from her, carefully sheltering her beneath his wings.
Then a bright and cheerful transfer student appears and offers Su Ruan a friendly hand, shattering the man's carefully maintained facade of calm.
The once-gentle protector sheds his disguise, no longer able to conceal his obsessive desire.
"Ruanruan, don't look at anyone else."
"Stay by my side. You can only belong to me."
