Fics like the ways a heart can hurt

Sanemi had always had nightmares. Mostly about his mom. Sometimes about his friends. Never about Genya. Because Genya was alive, and Sanemi had promised himself – promised himself – that Genya was the one who got to live. But then… Things never went the way that Sanemi meant them to. And Genya had different plans. -- In the weeks after the final battle, Sanemi struggles to come to terms with his brother’s death, drowning in nightmares, his heart as broken as his body. Stuck with the Water Hashira, Giyu Tomioka, at the Butterfly Mansion as they recover, Sanemi learns to navigate the fragile space between grief and healing and slowly learns that the happiness Genya wanted for him might not be as impossible as it once seemed.
