I actually kind of don't like her marriage to Zhuangzhuang? Whilst the puppy love was cute, and the affection between them is now there, it just feels as though Zhuangzhuang is way too young in comparison - especially emotionally.

I think Lizhi (and Zhuangzhuang) could have been written to have different partners much closer to themselves without impacting the quality of the story. But I don't hate their marriage, and it certainly felt like the destined path for Zhuangzhuang specifically.
