Recently, Si Yuchen blocked all channels through which Gu Xiaonuan could learn about the outside world. He had to do this to protect Gu Xiaonuan, so she wouldn't be affected by outside news and, in turn, have her judgment influenced, which would really not be good.
Si Yuchen has his own principles. If he had to watch his woman lose the chance and possibility to be with him, then how could he explain to his own son why his mother left Sea City when he was still very young?
Since Si Yuchen had decided to walk this path with Gu Xiaonuan, he was serious about it, and he genuinely thought this way.
When he's serious, he doesn't waver or doubt. As long as she's seriously thinking this way, then she must have a reason.
As for what others think of his authoritative control over Gu Xiaonuan, that's for others to consider.
Si Yuchen never cared about others' judgments of him. Otherwise, there wouldn't be so many people thinking he isn't someone easy to get along with.
