Even without the coach saying so, I had already decided this episode that I'll treat Suguru as the split-personality of Kakeru instead of some organ-possession phenomenon (pretty much like a certain character from Gundam 00).
That makes things easier to bear since I think of both sides as still being Kakeru...
The problem then, is the cringe I get when Leo orgasms every moment Suguru does something. That's pretty creepy.
