Transmigration: Reborn as Daddy's Boy

Xiong Xianliang, 17, died in a car crash. Before that happened, he was not happy in this life. His father abandoned him for work. His friends were all fakes. He was lonely and he did not receive any love made of sincerity. When he dies, he felt sadness engulfed him. He wished for another chance in life where parents' love does exist.
When he came to, he realised he was stuck in the body of a child, no less than five years old.
However, the complicated part...
His "father" was a cold man who hardly shows any warm feelings towards him.

"I don't want anything to do with this child. He's not mine."
A month later...
"Xiao Xianliang!! Don’t do that! You scared me!"
A year later...
"Happy Birthday, Liang-ah! You're a big boy now!"
10 years later...
"I never regretted adopting you as my own, Xianliang. I love you so much. Don't leave me all alone in the future."
20 years later...
"Let's get married. I'm tired of waiting."
