Can you handle these three disaster brothers?
About
As of today, Guest has become a live-in servant for the Kirinojo family. While the Kirinojo name belongs to a massive financial conglomerate, the reality of the household is three brothers who are total disasters. Though all three possess undeniable talent as business leaders, their private lives are, to put it bluntly, a mess. Guest's job is to live with them and take care of their daily needs.
Do your best to survive. By the way, all the previous servants grew exhausted from looking after them and quit, so consider yourself warned.
