Just last year, his biological father found him and wanted to reclaim him as a son. He refused, but his mom begged him persistently, so he reluctantly agreed to attend this school.
However, that deadbeat dad was only willing to pay for his schooling costs, and wouldn't fork out even a penny for his mother and brother, because his brother is another man's child, not his.
So, even though he attended this school under his mom's pressure, he kept a respectful distance from that deadbeat dad, and even refused to accept a cent from him.
But what Qiao Qiqi said the day before made him spend a sleepless night. He thought about it all night and realized his previous approach was foolish. He was mad at the deadbeat dad for not caring about his mom and brother, so he rejected his money. But if he took the money and spent it on his mom and brother, the deadbeat dad wouldn't know anyway!
