Regarding Sun Xinghai's death, Shen Siyuan felt surprised yet unsurprised.
Human emotions are very complex. Even though He Qingyan knew that Sun Xinghai killed her, she still loved him unconditionally, indicating that he must have qualities worth loving.
Moreover, judging by He Qingyan and the children's lavish tomb and the frequent signs of offerings in front of it, it shows that Sun Xinghai did care about her. Perhaps after killing her, he fell into a painful ordeal.
Because Zhong Xiaonan had said that ever since He Qingyan and the children passed away, Sun Xinghai aged visibly, his face became haggard and his hair went gray. Those who didn't know the truth thought it was because he loved too deeply and admired him silently.
Perhaps Sun Xinghai had already unknowingly fallen in love with He Qingyan, just that he wasn't aware of it and still yearned for the white moonlight in his heart.
Of course, this was just Shen Siyuan's speculation, but it was soon confirmed.
