*moves summary*

Think you're been mixing up the summaries with the first part, aoi. The summary for this one is actually:
MC as Miyu that he likes. Manager is forcing himself on Miyu, as he's about to be forced into fellatio, Miyu busts in with his body and drags him off back to his apartment. They get in an argument where the MC is mad that her supposed purity was all a lie, how many men has she slept around with etc? She says its his fault for not realizing that was all part of the facade. She's a cute girl so of course she would want to get herself a good looking boyfriend etc. Miyu says they'll probably switch back if they have sex, which they do, but when they wake up the next morning they're switched again.

They have sex again, this time from the back which she says makes her body feel the best and this time for sure they will stay switched back, etc. But immediately after switching back the 2nd time they snap back to being swapped a few seconds later. MC surmises that the reason its not sticking is he really loves Miyu and god keeps doing it for him. It ends with Miyu saying shes going to keep having sex with him until they actually swap back.
