Chapters 64/65 kind of ruins the main relationship. The fact that Leo seems to prefer FemFooly over the actual Fooly shows that the main romance is really one-sided on Fooly's part. You can say "Fooly-Sexual" or "joke chapters" all you want, the fact that chapters 64/65 exist shows that Leo is not attracted to (male)Fooly. From now on the idea that Leo is more turned on by women than (male)Fooly will be in the back of everyone's mind, no matter how hard the author will try to reinforce Leo's "exclusive interest" towards (male)Fooly. And the author will try to do everything to remind the readers that Leo only has eyes for (male)Fooly, the question is will that be enough to make everyone forget chapters 64/65?
