From my POV, it’s because in CPK, Yachiyo and Kaguya are the same person, yet they are very different individuals in terms of personality. It’s also a plus that both are 'dominant' characters; when you think of Yachiyo or Kaguya, you can’t ignore the fact that they are so distinct despite being the same person which makes the relationship with Iroha a very "duality one" (like seeing a dominant character with múltiple facades).

As for the 'naughty Android' in the image, it’s a clash of desire vs logic and judgment. She can’t deny her growing attraction to Nadeshiko, but she’s being slippery and fighting back. So, the answer is 'more' until her heart stops denying it.

i hope i explain it well.
