Ay bro, what the fuck?
Aiight naw, fuck Aoko for real. And I don't really mean that, I do enjoy these characters and how well written this story has been...
...But this is verging on drama for the sake of drama. And a level of self-sabotage I hate seeing.
Seriously: "I don't want you to go, because of my anxieties. But also, I can't go with you for a bunch of reasons I just made up on the spot. But also, I want you to go, instead of you staying, we should just break up." Unreal selfish behavior with no consideration for what her partner wants or feels.
