Not two, but three

Eren needed a way to prove to his 'friends' that he really had a boyfriend. Ever since day one he had always bragged about how great his was in comparison to their own. he just never thought they would ask to meet him in person...

Panicked, Eren runs up to the nearest boy in sight and begs him to play along. The only problem is, it's Levi. The school's personal 'bad boy', and the one person he's been in odds with since fifth grade.

"What's in it for me?"

"I...I'll grant you three wishes."

"As in you'll give me, or do anything?"

"Anything."
