I do have to say Usagi and Mamoru are obviously much more compatible than she is with Seiya cause he rentlessly pursues her and can't take a hint
stressed plus I think it's mostly lust on his part, and honestly Usagi isn't really the brightest bulb so she never really understood that Seiya liked her. Plus Usagi's heart belongs to Mamoru, and they both deserve it. I sometimes questioned if the Starlights were team players with the other senshi.
Anyway you left out my favorites
crying First off i'm a huge Rei/Yuuichirou (Chad to my dub speaking friends
wink ) shipper because he was SO cute!!! Plus he was totally under her thumb and did anything she said. I love how she was all flirty and kissed him sometimes (oddly more often when he was unconscious... she has a lot of trouble admiting to loving him). I saw this awesome site devoted to their love...
And here it is...
Focus: Yuuichirou & Rei Comeback edition!An amazing site that got me addicted to Yuuichirou.
Another that was left out is Ami and Ryo Urawa (Greg in the dub) he was so cute and really loved her so much. it woulda been nice to see more of him outside of season 1. He had a pretty big role in season 1 though, I thought it was a great relationship and certainly the best Ami has ever been given as far as love interests goes.
