Several years ago, Bai Chen lost his mother forever. At that time, he was no longer a naive child who didn't know what was happening, but he was already an adult who could understand the situation.
He knew his mother would not be able to open her eyes again, nor would she be able to smile at him again. Her body would be buried forever, and he would not be able to meet her again no matter how he begged her to wake up once more.
Bai Chen was heartbroken at that time, and he chose to lock himself in his pavilion after his mother's funeral. He refused when palace maids asked him to eat, and he did not answer when his servants questioned his condition.
At that time, Bai Chen only knew that he needed time alone to calm down, and that was the reason why he could understand Wu Jinhai's feelings at the moment.
