This is a story about possessiveness, where you become an idol's manager, go on a work shoot with her and while reminiscing about the shoot, dress her in her costume and have sex with her in a hotel You want to overwrite everything about the idol with your own desires.
Prior to this doujin, I don't recall seeing any Sora doujins of good quality (maybe that one where Senchou drank something Koyo made, but I'm not a big fan of that genre). This is THE definitive Sora doujin for me. And unlike the Lamy one from a while ago, this one is actually complete (Ayagi-sensei ran out of time and couldn't do a proper ending for that, sadly).
All praise Ayagi-sensei.
