C400 He Was in a Complicated Mood

It may be really hard to gain her trust again...

Just as he was about to start the engine, he felt a sharp pain in his chest...

It was so painful that he pressed on his chest, his face instantly turned pale.

Why is my heart so painful?

During this period of time, only by seeing her sad and listening to her complaints would he have that kind of real pain. Why did it hurt for no reason now..
