Uncle? Chapter 1

Young 10 year old Eren meets his mother's brother (His jerk uncle named, Levi)
for the first time. Levi comes off as rude at first, but after only 15 minutes he warms up to his reserved uncle.
Eren is 10 at first, while Levi is 19
I will wait until Eren is 15 and Levi is 24 before 'stuff' starts to happen.
Erwin is a pervert.
Just a straight up pervert.
Levi knows.
