Not related by blood / younger man / stepsiblings, 1v1, happy ending
After her parents divorced, Chen Aoqun gained a stepbrother, Qiao Ming, when she was nine.
At first, she found it hard to accept a stranger in the house.
But her little brother was so pretty and adorable, so innocent and pitiful, and he called her "big sister" in such a soft voice that eventually she began walking him to school every day.
They kept each other company for over a decade. Though they weren't related by blood, they were closer than real siblings.
Everything had gone smoothly for her since childhood. The only blemish was that every time she tried to start dating someone, things inexplicably fell apart.
Only much later did she learn who had been behind it all.
Her little brother, who had always been so obedient and sensible, suddenly went mad.
Chen Aoqun's head throbbed. She firmly rejected him, yet in the end they still had to go home and eat together.
When her brother knocked on her bedroom door in the middle of the night, she gritted her teeth. "Don't wake Mom and Dad."
He said, "Shh. Then keep your voice down, big sister."
