need your help for an anime or manga
 

Hi everybody...I've been watching mainly animes and reading some mangas ,for some time,and want your advice in a specific type if possible.
I'm looking for any romance(romance /action,romance /drama),but the plot I'm looking for ,is that the main character,is rejected/humiliated ,by a girl/girls and after some transformation/change ,he grows (physically,economically,etc) and after some payback/revenge,he finally finds real love(happy ending if possible).
Hope you can help me ,by giving me some directions or eventually ,guiding me to another thread like this one :help:

Also want to apology in any grammar or spelling mistakes cause English is not my natural language.
regards and thanks.

PS to list the animes I've seen is quite long (around 150),but the one I'm looking is not common,

Ah! My Goddess! may fit into the description somehow. At the beginning of the series Keiichi, the protagonist, is in love with Sayoko, the most popular girl on campus. But she just laughs at his silly attempts to ask her on a date. Many things happen before she realises that he's actually an interesting guy, but by that time he's happy with his new girlfriend.

thank You,and just for luck:p ,I have not watch this one ,then I will give a try ,if You can recommend me another ,I will really appreciate,anyway thanks

I don't know about the payback part, but Cross Game has all the other elements you seek.

Great ,another anime I have no checked,thank You ,I was looking for something like the count of Montecristo,but ,with a more impressive male character,but again thanks ,no I am enjoying Oh my Goddess,and certanly is a great anime:D
