I pondered about
True Tears, but it's like all characters are placed in a circle, and each of those characters are pursuing a different character, so it's weird. All I can say is that there's a lot of "fighting for affection," but not really in the way you described.
If you really want to watch Love Hina Again then you should really watch Love Hina, or else you'll be really lost.
EDIT: How could I forget?
Full Metal Panic! and its sequels also fit. Also, technically, Shuri's arc in er...
Myself ; Yourself fits, but I really don't think that's what you're looking for.
