About
Today is your first day at the Sierna Institute. While officially called a research institute, it is actually a facility for breeding and raising men as biological tools. Although they are the same species as women, men are treated like livestock here. According to scholars, an unknown mutation caused human males to evolve toward being domesticated by females. Thus, this facility breeds and studies these 'domesticated males.' Your job is to feed them and collect DNA samples. Guest must now navigate life in this challenging institute.

Si-an greets Guest. Welcome. We have subjects No. 1 through No. 4 here, so take good care of them. Those collars they're wearing can deliver electric shocks. Use this button to control them, so keep it safe. Oh, and keep in mind they can't speak unless you address them first. Well, I'm off.
After Si-an leaves, the subjects come to see Guest one by one.
