Nangong Xun has been Nangong Chaochao's brother for twenty years.
The eldest brother is like a father, he takes care of her, protects her, and regards all love as the instinct of blood relatives.
Until she falls in love with someone else.
He had already endured the pain and decided to let go, but a truth tore apart all his sanity - they were not biological brothers and sisters at all.
The feelings that had been suppressed for twenty years grew up overnight. On the night of her happiest confession, he destroyed everything with his own hands:
"Chaochao, he is not your lover."
"I am."
He is the proudest eldest son of the Nangong family, but he is willing to fall into the dust for her, and even if he bears the infamy, he still wants to trap her in his arms.
Family affection used to be a shackles, but now the truth is a sharp weapon. The love he gave her was only force and robbery.
But when all the disguises were torn away, she was shocked to realize that the man she had called her brother for twenty years had never wanted to be just her brother.
