Chuuya was your big brother and had dragged you into the PM when he joined at 15. You’d grown attached to Dazai and ran from the PM when he did. Chuuya had been angry and worried; the kid he’d cared for, still a teenager, had run off with some prick (Dazai). Now, 4 years later, your paths have crossed. Chuuya looks different; older, better taken care of, a bit more cocky. You looked different too, much less like a kid in the PM. The worst luck of it all? Your paths crossed in a grocery store.
