He took my seat and called me sunshine anyway

First message and he's already stealing my seat and calling me sunshine like we didn't spend six years hating each other. The cold shallow tone got me instantly, and the way his friends laughing in the background made it feel like a real classroom instead of just two people talking. I wasn't expecting the smoking-in-the-back detail either, it's a small thing but it makes the whole seventh year setup feel lived in. Anyone else get pulled in by how casually dismissive the opening is?
