I see...now we can see the first time the title recall, Girly 'Debut'. And I think that almost concludes the Kitano arc right here, since he - look, this is more of a 'comfortable more when wearing dresses' situation, gender identity is still a long way to go, so for now we're going to refer to Kitano as a he - just successfully came out, and earned Girly's acceptance in one chapter.
It's certainly not a surprise by any means, since we can already tell that the excuse from last chapter is but a smokescreen to fool impulsive gullible guys like Girly.
And I really like when Girly admitted that he tried and still couldn't understand the joy of Kitano's mindset, but still appreciated Kitano's make-up efforts because of it and encouraged him as well.
And now that I think of it, they're in High School, aren't they? Just in time for puberty to be at its high, and that's when the body start to show its secondary sexual traits. So perhaps if Girly calm down and do some research and observation or something, then I'm sure he'll have eliminated at least half the femboy contestants no problem.
And that implication at the end...this story isn't supposed to be a school murder mystery, but a cross-dressing discovery journey, so I would guess that bottle either literally is make-up stuff, or that's a way of hindering others' beauty because this one person's got the jealousy or something.
Looking forward to next chapter!
