(Bungo Stray Dogs/Jujutsu Kaisen) A Setting Sun for Dazai Osamu, My Dearest Love

A very late birthday fic... I'm ashamed... It's been a long time. I hope that I, Dazai, and any readers who need it can better understand loneliness and make peace with our own. About Tsushima Shuji, whose ability is The Setting Sun, becoming a curse spirit after his death, and reconciling with and saying farewell to Dazai Osamu. Super heartwarming, probably? OOC is unavoidable. Short story, wrapping up quickly. Theme: Making peace with love and loneliness
