Yep, unsurprisingly it was est em's last anthology contribution, "in the basement," for the Kemono Jingai collection: http://www.mangago.zone/read-manga/kemono_jingai_bl/mf/v01/c006/
http://www.mangago.zone/read-manga/no_99_ningen_omocha/ Not sure if this is the one that you're thinking of, especially since his salvation is... a matter of perspective and definitely time XD
Its funny, both of you guys gave a different story, neither where what I was thinking of, but both had minotaurs...who knew there were so many? lol ε=ε=(ノ≧∇≦)ノ
This is the one I was refering to, if anyone's curious: http://www.mangago.zone/read-manga/kemono_jingai_bl/mf/v01/c010/1/
Haha, it's a surprisingly popular topic! Although I wouldn't have that of that particular Kemono Jingai oneshot as a minotaur theme, since in my mind he looked more like a thestral from the Harry Potter series n___n
*clap, clap, clap* That was ...odd and awesome.
I feel like there was a similar story, but the minotaur was being used for shady purposes, and some rich guy bought him to save him....or something like that. (●'◡'●)ﾉ
