Synopsis
Playboy Shion takes a drug, wakes up as a girl, and gets hit on by his own partner Rui.
Shion and Rui are the dream team when it comes to hitting on women. Tonight was going to be another night of hooking up with girls for Shion, but he ended up taking a strange drug. When he woke up... he'd turned into a girl?! Rui came looking for Shion, but didn't recognize him, and started hitting on him... (Source: Suiseisha, translated)
