Shao Dong wanted to ask Shao Qihai why he had saved him. They had not called him 'Daddy' during this period of time. They had deliberately done those things to make Shao Qihai hate them and made up their minds to follow their mother if they divorced.
But why would both he and Mommy risk their lives to save them? Clearly, he had abandoned them previously. Even if there had been extenuating circumstances, it didn't change the fact that he had left them behind. They didn't intend to forgive him because they felt that he didn't love them enough and didn't value them sufficiently.
But now, why did he have to do this?
Shao Dong wanted to say something but didn't manage to, and tears rolled down his cheeks against his will.
Shao Qihai was initially worried that Shao Dong had been hit by the glass anyway. He hadn't expected Shao Dong to suddenly cry. This was simply a blow for Shao Qihai.
