Han Jisung is an adorable hybrid who has been mistreated his entire life, starved of both food and love, and eventually abandoned and homeless. One night, two kind men decide to help him. They take him back to their home and introduce him to their boyfriends. The seven men fall for the pouty hybrid instantly, taking him in and caring for him.

Humans and hybrids have a history of hating each other, leading them to live their lives with as little contact as they possibly can. But when the only all-hybrid university in the country closes due to a lack of funding, the university that Minho is ready to enrol in suddenly changes tradition and becomes the first institute to integrate hybrids and humans. When Minho then gets assigned a red-squirrel hybrid as his roommate, he wonders just on how on earth he'll be able to survive his first year of university. Or: What once started out as hate between a human and a hybrid, soon blossomed into something neither of them would have ever expected.
