Si Lingtian felt guilty towards Si Yuchen, so, even when he knew that Si Yuchen and Lu Xiao were at odds, he did not intervene from the Si Family's standpoint to prevent the conflict between Si Yuchen and Lu Xiao.
Anyone with eyes could see that Si Yuchen was doing this to stop Lu Xiao; he didn't want Lu Xiao to take Gu Xiaonuan away.
Gu Xiaonuan was Si Yuchen's wife and also his granddaughter-in-law. By rights, Si Lingtian also liked that child a lot, but somehow, recently, Si Lingtian felt more regret.
He valued Gu Xiaonuan's character and knew she would certainly be a good wife. Finding such a good woman for his grandson put his mind at ease.
However, after Si Yuchen turned against him for the sake of their child, Si Lingtian had a change of heart.
Because love, this thing, can indeed cause drastic changes in people.
It was also because of love that Si Yuchen openly turned against him, unable even to understand the difficult choice he had to make to save Si Yuhao.
