Empty (Without You)
Any time Geto suffered or struggled because of his presentation as an omega he thinks back on the day he saw the boy with white hair and bright blue eyes and blames him for making him an omega.For burdening him with this role.And a voice, that he long ago identified as his inner omega, cursed that boy for not protecting him.
“I’m sorry,” Satoru whispered, knowing those words would likely do nothing for the pain of the last ten years they spent apart. “I’m sorry I wasn’t there for you.”Of course they suffered without each other.They were, after all, fated mates.

Or, the one where Satoru and Suguru are unknowingly fated mates, separated for a decade, and unable to find happiness without each other.
