That kind of his home with some conversations he'd had with his senpai before coming here. About how he felt like no matter what he does he just makes a mess. Makes things harder for people in his life. His mom, mostly. It's hard, always being a screwup and not really knowing how to fix it. Mostly he just keeps doing the same stuff like get in fights and skipping school because he gets so pissed off by screwing everything up he just keeps letting it out by doing the same dumb things.
"Damn, that's some pretty heavy stuff. So you guys saved the world together?" Seems like the story doesn't just end there since the video is still going.
