I still think this manga is a little fishy. And when I say this manga, I mean Nana's friends. And by Nana's friends, I mean her boyfriend and two friends she followed to Tokyo.
I'm just prepping myself for the chapter where they chew her out cause I seriously do not believe they're okay with her being there. It almost seems like they left friendly, found out they could make it on their own, thought they were mature, and became stuck-up douchebags. Idk, that's how I see it.
