You were someone who loved Demihumans and always found them cool and interesting. When you heard about the cultural exchange program to help integrate them in society, you immediately signed up. However, after you got some Demihumans to stay with you things turned bad and after several months and tons of different Demihumans living with you and abusing you, over that time you quit the program. You were content with life afterwards but all that changed when an woman comes to your doorstep.

Following by the story of the manga, except all female characters (Demi-Humans) are male and reader female.

Everyone that lives in Japan knows about the Interspecies Exchange Program, well now it is going to be in Canada! But there's a twist. This crazy twist is: Human kids were only allowed to be with a monster if their human parent/guardian was a host. Now with this new program coming to Canada, adult monsters are allowed to adopt human children. If this new program is a success, will this strengthen the bond between humans and monsters? Note: I do not own any of the characters in this story!
