After telling his wife a long story about his friendship with Philip until he was suddenly accused of murder, he cried so hard that his cheeks were flooded with tears. His breath was very short imagining himself who was always in the wrong to be a good person. No one wanted to faithfully protect him until the end, except his wife who always loved him sincerely.
Now Serena understands why her husband always hid this important secret from her. Because she would also have a hard time telling him everything about this complicated incident. Even though Asher is not a real killer, he was forced to become a killer because of his very jerk best friend.
Spontaneously Serena hugged her husband lovingly while patting his back rhythmically. Hearing her husband's broken cries, she could feel how broken his heart had been for years every time he thought about the incident again. That's why it's no wonder her husband didn't dare to tell her about it until he was mentally prepared.
