real talk.
best chance? in highschool or college.
they start to get curious, but not yet tainted by the dark side of society.
but, if you yourself is already an adult in society, that would be a problem.
I mean it sounds weird, but it is true, the biggest slut I've ever met in my life was my classmate in (13-16yo) 9th to 11th grade, I'm pretty sure everyone of us smashed... except my pure hearted felllow JJ or people with normal gf's, but they could've cheated, who knows?
But... I never met a slut+love striked girl like the one in this Manga...
