Deep Fog Kiss

At the age of ten, Jiang Li, an orphan from the Jiang family, was taken away by the Gu family, a top wealthy family in Jingzhou, after two years of wandering. Her guardian was changed to Gu Zhishen, the second young master of the Gu family.
The young man, who had just turned eighteen, was handsome and refined, arrogant and unruly to the point of being overbearing. He looked down at the pitiful little girl in front of him with a cold and disdainful gaze.
Jiang Li desperately tried to hold onto this hard-won sense of peace. She was obedient, polite, and timid, her eyes filled with tears as she called out to him, "...Brother?"
He chuckled, his hand on her head patting her like he was petting a dog. "Lowering my seniority?"
later,
On her eighteenth birthday, a torrential downpour poured outside the window. Jiang Li rolled over and climbed onto Gu Zhishen's bed, wrapped her arms around his lean waist, and stubbornly tilted her head back to bite his thin lips, engaging in a passionate kiss with him.
The man gripped her waist tightly, his breath hot and penetrating her bones.
Rumors circulated that Gu Zhishen, a noble young master from a top-tier aristocratic family, was aloof and unapproachable, and never approached women.
Only Jiang Li knew that he was a heartless scoundrel and a womanizer.
Jiang Li persistently pursued him for two years, but she couldn't even stir his heart. So she decisively broke off all ties with him.
......
Later, Jiang Li appeared in front of Gu Zhishen, affectionately holding her boyfriend's hand, and called him with a smile, "Uncle."
That night, in the cramped room, the man's dark eyes burned with jealousy. He forcefully and domineeringly tightened his grip on her slender waist, pinning her against the wall. "Uncle? Not my fiancé?"
