L's Little Omega

This is an Omegaverse fanfic, meaning Alpha Levi, and Omega Eren. I am using the band No Name where Levi, Hanji, and Miche all play together.

This is going to be R18+ so plenty of smut, Boy x Boy, don't like, don't read.
There may be some triggers for some people, aggressive play, tying up, BDSM play, things of that nature so please tread lightly. I will try to warn when I will write those in said chapters.

Okay on to the actual description if anyone actually reads those haha,
basically Eren attends his first No Name concert just as he turns 18 and doesn't realize Levi or "L" is his mate. L picks up on his sent but can't pick him out in the crowd but becomes distracted during the show but does his best to continue. After the show Levi does his best to try and find him but Eren ends up going into his first heat... will Levi be the first Alpha to get to him???
