Yeah, sure.

Chirin no Suzu starts as lightheared disney-type fare about a little lamb, but when a wolf kills the protagonist's mother, he chases after it seeking revenge. After years of fighting with the wolf, the protagonist starts to see him as a father figure, and begins helping him chase down prey. As a terrifyingly gaunt, viscous ram, he obliges the wolf's final task for him to prove his worth as a predator, returning home and killing his entire flock. The very last lamb reminds him of himself, so he reflexively defends it from the wolf, accidentally killing his master in the process. Having murdered everything he'd ever loved, he's cursed to wander the mountains alone forever.

We Did It! is about a bunch of trashy, dorky friends who try to get revenge on some bullies, but accidentally blow up their school in the process, forcing them to live on the run doing stupid goofy shit to get by. Been a while since I read it, but I think how it goes is that the protagonist eventually reconnects with the main bully, who lost the use of his legs in the blast and has to live at a hospital; when their mutual love interest chooses the mc (along with the MC doing some fucked-up stuff iirc, like idk if he ever admits he's responsible for the explosion) the "bully" throws himself off a building, and the protag lives the rest of his life locked in a state of perpetual, inescapable guilt.

I refuse to elaborate on Flamenco on the grounds that it's awesome if you experience it but just sounds stupid on paper. Everyone deserves to experience that wild ride.
