Because of their father, Wiryo was forced to be responsible for their future business since he was a kid.
Wiryo erased everything about their father. He didn't want to meet their father even when he was on the brink of death. The Wenzel family too decided that they no longer have anything to do with their disowned son. They poured all of their attention for the sole grandchild, Wiryo. The Wenzel and Wilaus family only came to the funeral and paid no mind to the daughter he left behind.
It left Clara and her mother to fight for their survival. Even though in the end, Wiryo cared for her step-sister's life in the dark. Without telling anything, he paid for her education and gave her financial support in secret.
