What Su Yan really wanted to say was that Jiang Zheyu didn't have to go see the meteor shower with Zexun. She could wait for him to return, and he'd go with her instead.
But in the end, Su Yan didn't say it. It would have made him seem far too selfish.
Besides, after Jiang Zheyu was kidnapped, Su Yan realized his Yu Yu needed more people to protect her. She should marry more Beastmen, surrounding herself with powerful ones for her safety.
Su Yan was also reluctant. He wouldn't be the one to persuade Yu Yu to marry more Beastmen.
And he probably shouldn't stop Yu Yu from spending time with other Beastmen, either.
But people are selfish. He knew it was wrong, but he still wanted Yu Yu all to himself and instinctively pushed away any other Beastman who got close to her.
In the very end, Su Yan still couldn't bring himself to ask Jiang Zheyu not to go see the meteor shower with Zexun.
The three of them returned to the Imperial Palace together.
