The Monster

 "My father is not a gigolo, he... He's a great hero!"

Olivia Walker had always been timid, but whenever she heard someone insulting her father, she would always muster up all her courage to stand up for him.

 She knew that the words 'gigolo' did not sound nice!

 "You bastard, don't you dare say another word!!!"

Issac Davis said fiercely, "If it weren't for you, I wouldn't have suffered so much for so many years!"

 He had blamed everything on Oliver Walker.

 If it weren't for Emilia marrying Oliver Walker, Olivia Walker wouldn't exist.

Without Olivia Walker, Emilia would have married a super-rich man. Why would they end up being kicked out of the Davis family?!

He would have been the head of the Davis family now!

 "I... I... My father is not a gigolo!"

 "I'm not a bastard either. I am the daughter of my parents!"

 Olivia Walker's eyes were filled with tears, but she still shouted out boldly!
