|Most red haired manga characters seem to be female. The few male characters I can remember don't often end up with the girl. (If you'd like me to recommend the ones with minor male characters I can, though). And you've read the first three manga I thought of (Fruits Basket, Rurouni Kenshin, and Futari no Renai Shoka).
A Stranger in My House - the male lead has red hair. It's a webtoon. I haven't finished it yet, but it seems like it will have a happy ending.
My Beautiful World - the male lead has pink hair (which is commented on by others). I'm not sure if that's close enough to red for you. It's a romance webtoon with another plot that is of equal importance to the romance.
Golden Days - the love interest has red hair (which looks really natural compared to most manga red hair). It is a shounen ai (the romance plays a minor role in the plot but is definitely memorable), so I'm not sure if you would be interested. Also,
Spoiler (mouse over to view)
The ending of the romance is more complicated than ending up together or not.
