Fics like Under The Mourning Sun

[contains slight manga spoilers] "I'm sorry," he atoned, lowering his eyes to the ground. Those ocean blue eyes that canopied the mayhem that Satoru Gojo cultivated. His agony was deeper than ocean beds, stronger than ocean winds, and colder than glaciers. Suguru Getou was like his family, even more than that. But the jujutsu world almost fell into the hands of peril, and he needed to protect it; he needed to protect you. / You were inseparable from Gojo and Getou during your jujutsu high days, and you three share an unshakeable bond. Until your fates collide and morph into a havoc of remorse and anguish. Amidst grieving the one you lost to darkness, you'll find the one you'll love.
