我的一个多重人格朋友

This game is an AVG game that involves deduction and decryption. He Zhou has 7 different personalities, which alternate seven days a week. Players will play as a detective and deduce the truth behind the horrifying cases surrounding He Zhou through the diary he left behind.
Game background:
My name is He Zhou. My lifetime is one seventh that of others, but the thickness of my life is seven times that of others. Because there are seven 'me' living in this body. But don't misunderstand, we are not like those violent and unreasonable split personalities in movies. In order to better coexist, we named them Monday to Sunday respectively. In fact, we also follow a 7-day cycle and have our own independent lives. We have never met in person before, and the words on the sticky notes are the only way we communicate. Besides that, everyone has a diary to keep track of their little secrets. In short, I have seven selves, which gives me a richer life and a lonelier life. The excitement is mine, and the loneliness is also mine.
