mhhh when you think about it, there are a lot (though finished could be a prob.)
here some I like
http://www.mangago.zone/read-manga/senya_ichiya_shitone_no_himegoto/
http://www.mangago.zone/read-manga/awairo_emaki/
if I remember correct its pretty much finished (even though marked ongoing)
http://www.mangago.zone/read-manga/sweet_heart_trigger/
I think its marked ongoing bec. there is a second vol. but first is finished

One of those mangas I wished would never end.
Im tired of the same old yaoi plot where the seme is in love with the uke and kind of forces him into a relationship. Im looking for something unique, does anyone have any recommendations? :)
