Lmao what a crazy turn of events. I guess him suppressing his libido all this time makes more sense than not having a libido whatsoever. But for it to take shape and manifest as a fuck boy alter ego... well... definitely was not in my bingo book.
Might be obvious but worth point out. Looking ahead, this is for Kuyou to overcome his aversion to sexual and romantic desire. The alter ego forces confrontation with parts of himself he kept locked away. He's been trying to ignore it all this time stating that he doesnt understand "that stuff" and is simply a practitioner carrying out treatment. But by learning to accept and live with his libido and interest in the opposite sex, we can finally get some romantic progression with Aoba and Aroma.
Thanks for the chapter!
