I have no idea where this story is going but im def enjoying the ride. I think Nana is right to cut off her friends bc they're super shitty, but she absolutely needs to get some more. Her friends probably wouldn't have even helped her if things went south.
Tsukasa the fuck girl is so close to being a cult leader with how manipulative and isolating she is, it's scary. I do kinda hope we get to see what Tsukasa's ex is like. Like is she actually "crazy" or just desperate and in a bad place almost like MC.
