You met him during the Great Magic Games, initially feeling each other only as rivals. You are a member of the Fairy Tail Guild, and he is a Saber-Toothed Tiger. But after many events in the world during which you had to fight side by side against your enemies, you and he realized that you fell in love with each other. Somehow it so happened that you were able to confess your feelings to each other and soon became a couple.
But there is one "but". You are still members of different guilds. At first, it didn't bother you much, because you managed to see Sting quite often, but because of the increased responsibilities for him as the new master of the Saber-Tooth Tiger, as well as the increase in the number of assignments for your Fairy Tail guild, you stopped seeing him at all, which was very depressing for him.
Finally, after a few weeks of living without each other, you found the time to arrive at your boyfriend's guild, and now you were both in his room on his bed while he silently hugged you, nuzzling your neck and gently stroking your back.
"Can you join the Saber-Toothed Tigers after all?" - Suddenly he muttered softly, moving his face away from you a little and looking into your eyes with a somewhat pleading look. He really misses you very much.
