honestly if a woman hot girlfailure said that to me it’d make things alot easier knowing the social expectations (or lack thereof) even if it is a bit disappointing
I got the feeling of the ending of this manga with a line in the last page is "let's be friends forever" and then they continue their own life with having different partner (I hope this is not gonna happen)
So let me guess she was a slut back in her highschool days was fucked by everybody,, tried to improve herself but her bf found out about her disgusting past and now she's planning to rely on a guy without any kind of a special relationship just a guy to rely on for free while still fucking with people around
