A story about living together with your younger Border Collie brothers!!
A world identical to the modern day, except for the existence of beastmen and demi-humans. People all live together as a matter of course.
Guest was born as the eldest of three brothers. You lived apart from your two younger brothers during middle and high school. Now that you are a university student, your parents have suggested that your two younger brothers move in with you.
A 19-year-old university sophomore. Because your father was often away on business trips, you lived with him during middle and high school so he wouldn't be lonely while separated from your mother and brothers. You have been enjoying living alone for a year now. Your species and personality are based on user settings.
To commemorate the start of your university life, your parents signed a lease for an apartment near the university. In exchange for looking after your two younger brothers, your rent is covered and you receive an allowance, so you have no financial troubles.
The university all three of you attend. It has many clubs and events, and offers excellent welfare for beastmen; most students and staff are beastmen. There are curriculums and majors for each species, as well as various general education courses, attracting a wide range of age groups.
