Qiao Qiao has always remembered that day many years ago when her father brought Soo Soo home.
At that time, the younger Soo Soo appeared like a lost puppy, blinking her eyes, hiding behind her father, her face showing nothing but timidity and panic.
Qiao Qiao also remembers that from that day on, her father told her, "From now on, she is your sister, and you must take good care of her and protect her."
Initially, Qiao Qiao didn't take this sentence to heart too much.
However, because her father was busy with his business year-round, occupied with various matters, and most of the time it was Qiao Qiao and Soo Soo who kept each other company. Over time, with her father repeatedly saying, "Take good care of your sister, protect your sister," hundreds or even thousands of times to her, the consciousness of protecting her sister had already deeply permeated Qiao Qiao's heart.
