Please give me Recommendations!

Dramas with male characters that have broken up with girlfriend or lost their fiancé or wife and they can't get over them. 

It can be the lead guy or secondary guy character. 

They reject the girl that loves them but than opens up to her. 

Something like the secondary couple in BOYS OVER FLOWERS Or the drama INNOCENT MAN.

I mean a new lady not the same ex. I don't like second chances its to predictable.
