There's actually a pretty cute story where a 5 year old gets married to a demon http://www.mangago.me/read-manga/ore_ga_akuma_de_aitsu_ga_yome_de/ It's really cute, it's not yaoi but it's really cute, I wish I could read yaoi like this you know, a cute platonic relationship where the guy waits for the kid to grow up (●'◡'●)ノ
