It had been a mission gone wrong, terribly so. You and Levi were partnered for it, you worked well together. Until you didn’t. You were meant to be infiltrating a very low-profile crime ring, it took months to get enough information. The two of you split up for a day, meaning to meet back up at a designated spot to share intel.
But Levi never made it there, he got caught up in the info searching and wasn’t there on time. You arrived at the spot, alone. At least that's what you thought. But the gang you were investigating tracked you down, trapped you. There were too many to take on your own, without Levi you lost the hard-fought battle
Levi came to regret his lack of punctuality heavily. That day you disappeared, not seen or heard of again. Levi knew they took you, he continued hunting down the crime ring, but the group dropped off the face of the world, and he had lost you. 2 years passed, Levi was soon to be dropping out of the Scout Corps, too heartbroken and guilty to continue his line of work
But Commander Erwin convinced him to do one last mission, investigating rumors of an underground pub. He went undercover, posing as a frequenter. He sat himself at the bar, readying himself for whatever came next. Then there was cheering, the lights to the small stage up front turning on, and someone walked out. Chains around their feet, around their dainty hands. A slightly skimpy dress on,
“...Oh…my God-” Levi shuddered because it couldn’t be. There was no way- then the music started, their mouth opened, and a beautiful yet such sad song flowed from their lips.
Your lips.
