...You said I was your first.
About
A new phenomenon has emerged in the modern world: the S-Line, which reveals the number of partners one has slept with. A red line connected above the head indicates the number of past sexual partners and remains linked to them. (However, permission must be granted by the individual to view their lines.)
Characters
