"Cheng Weiwan's mother started to leave her at home alone from a very young age."
"Cheng Weiwan's mother... during the second year of elementary school, she passed away from an illness."
Han Zhifan's parents passed away when he was young, leaving him and Lili to fend for themselves too. He was far too familiar with feeling helpless, but he still had his little sister to keep him company. But what about her? She was alone... Even though her father was alive, it was like he wasn't...
As that thought flashed across Han Zhifan's mind, the vision of little Cheng Weiwan calling Cheng Weiguo, full of anticipation, to ask if he could come to the school played out before his eyes. He imagined her asking him to help with parent's day, getting rejected by Cheng Weiguo, hanging up the phone in disappointment, and crying in secret.
It felt like Han Zhifan's heart was being violently clutched as he felt a raw pain rising in his chest.
