My Sister’s Best Friend Exposed My Secret Identity as the Black Knight

Black Knight Ning Chuan, instructor of the world's top assassin organization, has retired and returned to his hometown, hoping to live an ordinary life and take control of his own happiness.

He adopted seventeen children on his own, hoping to atone for the sins he once committed.

After two years of city life, Han Ni, his older sister's best friend, was caught in an arranged marriage between business families. Unwilling to become a puppet of her family, she asked Ning Chuan to pretend to be her boyfriend.

Han Ni's father came to visit her, bringing along a tall, handsome young man.

Ning Chuan and Han Ni greeted them as a couple.

Han Ni's father turned deathly pale with shock. "Instructor...!!!"

Ning Chuan: "I'm your future son-in-law. You're calling the authorities to arrest me? How can you... how can you do that to your daughter?"

Young Master Zhou: "President Han, didn't you say Han Ni was single? Who is this guy?"

Han Ni: "Him!? He's my bo... boyfr... He's my man."

Young Master Zhou: "Dead!"

When the four sat down to eat, Han Ni's father was so nervous he trembled even as he picked up food with his chopsticks.
