@yeetyeetcheese Despite anime/manga making it more overblown than real life, the idea of very unambiguous confessions of love is a very real thing in Japanese culture. If you don't put it into words explicitly it's generally assumed whatever relationship you have is at best a non serious fling...
@Anonman88 Calling it now btw, Nagi's biomom is Hiro's mom's sister/cousin.
My evidence is their similar hair color/style and how Hiro's mom acted towards nagi at their first meeting.
