Integrity is more important than anything else. If you believe you don't even have the most basic integrity, then what else is there to say?
Zhang Zhentian never expected that his father had already thoroughly investigated the matter, just waiting for him to fall into the trap. Perhaps his father really didn't want him to return to his home, or maybe all of this was the consequence he originally had to bear. Who could he blame now?
Even so, he was still unwilling. He was unwilling to be driven out of the house by his father and never return. Clearly, the mistake he made in this matter wasn't that big, but why should he be expelled from the house for a lie, never to return for a lifetime? The mistake he made wasn't that severe. Was it wrong for him to hide the truth to help his wife? Was everything he did in his father's eyes really that unbearable, really never right?
