From YahmeeTeeh Scan:

The virus that infects only Ω spread, and the only Ω that survived was Shu Miyamoto, who has an antibody in his body. It was the end when he was isolated by a government research institute and forced to have children with α, but Honda, who was selected that day, was in heat at the moment when he met, unlike anyone else so far. It ends up......!

The end that drowns in lust, seeking Honda of α with instinct. I'm convinced that this person is my destined partner, but what is the relationship between the two who can't take turns?
