Looking for novels where the MC had a tragic past. For example, he's the last survivor of his family who were massacred. Or an ex-soldier whose comrades died in battle. Shit like that. This must actually come up in the novel instead of coming up once or glossed over. And when I mean come up, I mean actually talked about to other people rather than kept solely in the MC's thoughts, never telling anyone. Also, this can be modern world, transmigration, fantasy world, but preferably modern world. Thanks
