Finally got caught up on the manga in my wish list so I'm looking for something new. More specifically I'm looking for a romance similar to:

Skip Beat!(The general plot is funny and interesting which is great but I really like the relationships here because it is unclear who the MC may wind up with and it seemed like there are multiple characters the MC could end up being with, )

Horimiya(The plot is interesting and I just love the relationship between the two MCs. And the change that occurred in the latest chapters makes this one of my favorite manga right now)

Thanks

I should proof read my comments more, but I won't...
So keep in mind I'm filled with typos

Yeah, I'm not really sure what you're looking for either... but here are some where it's not obvious who she ends up with:

Show Princess
Scarlet Palace (At least, I don't think this one is obvious, cause I can see this going either way.)
