It's Modern Au, and basically it's summer, Jean and Eren have been dating since freshman year, after this summer it'll be senior year. Levi, is also going into senior year, he's liked Eren since sophomore year. So this summer he wants to be able to at least sleep with Eren. Of course Jean is aware of this, he's determined to keep it from happening. Levi throws a lot of parties and Eren is vulnerable when he's drunk. Will Levi reach to his goal this summer and tear Jean and Eren apart? Or will Jean keep Levi from tricking his lover? - Yes there is Lemon/Smut in this, you have been warned.
