The Promise [giyushino fanfic]

War doesn't wait for confessions. On the eve of their most dangerous mission yet, Giyuu Tomioka and Shinobu Kocho find themselves on the edge of something fragile - a bond quietly forged in stolen glances, late-night tea, and words they were too afraid to say out loud. They make a promise beneath the wisteria: "We'll both come back alive." But when the dawn breaks, only one of them returns. This is my first finished book, hope u enjoy it! (i suck at writing fight scenes, i got lazy so theres a lot of time skips) NO NSFW
