I'm a university student studying abroad in a neighboring country, but my life isn't as peaceful as it looks.
One night, I come home late and run into a catgirl. After spending several days together, she starts looking at me in increasingly strange ways.
Next door live two yandere sisters. The older sister likes her younger sister, and the younger sister likes me.
My childhood friend, who is studying abroad with me, is known by everyone as a sweet, airheaded girl. Among them all, she seems the most normal.
Besides them, I also have to deal with the neighbor's little boy, the sleazy boss of the boy's mother, street thugs, and a muscular man with no face.
It looks like life in a gal game... right?
At least, that's what I thought before my own ending arrived.
The catgirl dies horribly before my eyes; the older sister kills her younger sister with her own hands; my childhood friend becomes an empty-minded puppet; and a System that can turn back time makes me relive my breakdown again and again...
After going through all this, what exactly am I, now that I've graduated from university?
