a!Tohsaka Eiji x o!Mitsuya Jin/Takashi
a!Gino x b!Luca
Mitsuya, abandoned by his mate a decade ago, is cursed with unstable heats that can only be tamed by sleeping with an alpha. When Eiji appears during a very bad situation, the two end up getting close only to realize they're soul mates. Mitsuya can never bond another alpha again but Eiji cares about him far to much to let that stop their happily ever after.
Goodbye to Destiny
