Yes, hands down to Sakura Gari. :) You better ready your heart. And it won't solely bring twinge in your heart but I think it's safe to say that it will make you feel murderous at some point. There won't be only pain, but there'll be anger and pity and all that snowballed in this really beautiful story.
I have a few titles that made my heart squeezed. Not over the entirety of the story but at least I had that feeling at some point.
Koi To Wa Yobenai
End Game
Breath
Hana Sakasemashou (shounen-ai/incest)
Kanashi Kotoba
Cut and Overdose by Touko Kawai
Wonderful Days
Hope you can find some titles to your liking. I'm kinda lazy to browse my folders. Just too many titles! :P

Anyone can recommend angsty yaoi? like when you read it you feel that addictive twinge in your heart? Or am I the only one who feel that? =))) But anyway mangas like Sunao ja nai ke do (and other stories in warui series), Kachou Fuugetsu (third story), Dekichata Sitsuji... etc. I just need the angst! But not those type that would make me cry like dog style (that made me cry buckets )
I just want to feed my masochist self today :>
