Looking for a romance manga where one of the mc is very strong (over powered) and preferably becomes a lonely soul with jaded personality that have a sad/tragic past.

The other mc is someone who finally melts the OP MC's heart and he/she becomes very sweet and loving to her/him. I would prefer it if the mc isn't the typical damsel in distress, not stupid, and actually helping the op mc by being himself/herself..

They trust each other, save each other, rely on each other, and slowly overcomes his/her trauma. Overall a beautiful story about trust, friendship, and love. Something with happy ending if possible..

I'm fine with any genre as long as there is romance in it (⌒▽⌒)

For example, something like the classic

http://www.mangago.me/read-manga/gakuen_alice/
http://www.mangago.me/read-manga/fruits_basket/

Or the relatively new

Or the newest

Or even these amazing BL

And many moree!! (Too lazy to search the manga) ╮(￣▽￣)╭
Anything that I can re-read and feel content after (▰˘◡˘▰)

Though nothing like

Because I don't want to torture myself with a ship that doesn't sail... No love triangle is better (￣∇￣")
Or http://www.mangago.me/read-manga/skip_beat/
Where the romance haven't even started (╯°Д °)╯╧╧

Sorry for the long post... and rant... (≧∀≦)
Have a good day everyone!! I'm looking forward to your recommendation~
