Now, in Zhang Ni's heart, Zhang Yichen is just a selfish father. His selfishness has achieved its results; for his own purposes, he resorted to any means, not hesitating to hurt his own family, the relatives around him.
He feels that now his own father is simply terrifying, willing to only consider his own interests; in his inner world, there are only his interests. For his own benefit, he could hurt everyone around him.
He no longer understands what he has done all this for. Perhaps his actions would hurt those who love her the most, but it seems he no longer cares. Even so, he still does what he wants; he has abandoned his entire family, treating everything everyone in his family says as mere wind. He is no longer the father he used to be; he has changed, becoming entirely different, becoming ruthless and cold-hearted. Is this really his father? Why does he live like this now?
