A.) We are crazy fangirls who love gay, lesbian, and straight couples (Mostly gay/yaoi)
B.) People started seeing how they are very similar in personality, strength, combat, and other stuff.
So, at some point, it became a ship.
The Ship NameEdit
The MIK/A comes from Mikasa and the A/NNIE is from Annie, obviously.
The Top and the BottomEdit
Okay, I think it goes either way, but most say Mikasa would be seme while Annie is the uke. But I personally think Annie could be seme, but the way the shipname is made, I am turned down by most.
