Lost in the Meaning (Ereri/ Eren x Levi fanfic)

(Current day FanFic)
The last week of school has finally arrived, leaving Eren Jaeger at the fit of celebration. And celebration indeed.
A surprise substitute teacher fills in for math the last week, by the name of Levi Rivaille. Good looking with an attitude that could make the dark shudder, Eren is amazed and, he can't quite put his finger on it, but curious.
The usual end of school party rolls around. A familiar face is found.
Is that...
Mr.Rivaille? As a bar tender??

(WARNING: this fanfic is no chill, this is a no chill zone, shits about to get a little weird.)
