You Were Supposed to Take Your Sister to School, but You Fell for Her Best Friend

[One Female Lead] [Romance and Daily Life] [No System, No Rebirth] [Light and Sweet Romance]

In his sophomore year at Peking University, Lu Cibei was forced by his mom to take his younger sister, who was just starting middle school, to her school orientation.

At the school gate, his sister stubbornly insisted on waiting for her best friend. No matter what, she refused to call him "Good big brother" in exchange for some snacks.

Lu Cibei turned around with the snacks and walked over to the beautiful little girl staring at him in a daze. "Call me big brother, and this bag of snacks is yours."

The rich heiress Su Niannian blushed, then stammered in a soft, sweet voice, "B-Big brother."

Lu Cibei grinned. This little stutterer was so cute!

From then on, Lu Cibei developed a mischievous habit: teasing this "little stutterer" every day.

His sister, Su Tingwan, was furious. "Lu Cibei! My best friend isn't a stutterer! She just gets shy when she sees you!"

Years later, Su Niannian got into university and cornered Lu Cibei against a wall. Her eyes danced with emotion. There wasn't the slightest trace of a stutter in her now.

"Big brother, I'm all grown up. How much longer are you going to treat me like your little sister?"

Lu Cibei was dumbfounded. Wait, I treated you like a little sister, and you've had improper designs on me since you were a kid?!

Lu Tingwan was even more dumbfounded. I treated you like my actual best friend, and you want to become my sister-in-law?!
