Su Wan, the sole heir to the top wealthy Su family, is a demon king who is spoiled to the core. She has a beautiful appearance but a perverse and violent temper. Those who obey me will prosper and those who go against me will perish. She never knows what the word "condensation" means to those who don't like her.
Lu Zhiyan, the leader of the Lu family who was evenly matched with the Su family, was cold, dignified and ruthless, but he gave all his patience and indulgence to Su Wan. If she wants stars, he won't pick the moon; if she stabs someone, he will carefully clean the handle of the knife when handing it to her.
From climbing trees together in crotchless pants, to the lipstick marks secretly imprinted on the collar of the school uniform; from the ambiguous test of getting wet by the pool, to shielding her from all troubles without hesitation at the cocktail party - this pair of childhood sweethearts that are envied by everyone have already left deep-rooted marks in each other's lives.
She was arrogant and overbearing, but she hid her secret dependence in front of him; he was silently guarding her, secretly in love with her for many years, only waiting for an opportunity to completely capture her in his arms. When temptation tears away the disguise, when ambiguity breaks through the boundaries, this entanglement that started when they were young will eventually burn into a prairie fire.
"Lu Zhiyan, I want you to always only look at me."
"Wanwan, from beginning to end, I only have eyes for you."
This is a story about a vicious and pampered eldest lady, and her loyal dog knight who "passes the sword" without blinking, from childhood sweethearts to passionate love.
