Ren Weimin did not lie but he did not say the truth either. It is not his fault if his mother had thought what she wanted.
As soon as his mother nodded her head, he bent his torso to grab the phone that was lying on his bed, which fell earlier at the impact of his mothers slap.
He unlocked the phone and without showing his screen to his mother, he dialed his father instantly and placed the phone next to his ear.
This is his last and final chance. His father is now the only hope that he could see at this moment. He trusted his father to answer his call and enter the house within the next few moments and solve everything for him.
But the young Ren Weimin did not yet know that the expectations may not always meet the reality. Being optimistic about his situation, he called his father with so many expectations and hope but he did not really expect that the phone would not be reached.
