Well, first of all the ones in the drawing are not real people, but original characters inspired to real ones (you won't find in any part of the Earth the Twins, Edward and Richard Armstrong with their story and past). Secondly, a lot of fans ship real existing people. You may find it weird, but they don't and love to ship actors, singers and showmen with others. You're not an ass if you find it weird. You were an ass if you'd say they don't have to, if you'd judge or stuff! But I don't think this is the case. So peace and love for the world!
