Favorite paired endings and why?

Firstly with M Byleth, but then also couples you really like their supports or endings.

I saw a post a few days ago about somebody saying Byleth marries Manuela out of pity, and upon completing those supports I find that kind of true.

When I did my first plays years ago, I did Lysithea and Edelgard who both have so much stuff happen to them that it made the conversations carry more weight.

I was planning on S supporting Shamir but her A Support kinda made me feel like we’re just a replacement for her first love and it had me feeling weird about it.

So who do you think seems to have real chemistry? Trying to plan out future support routes. I’m on Blue Lions and I like Felix and Annette, and Ashe and Petra probably the most so far.
