Guys, I don't think it's incest yet (maybe I'm coping) but, i think series has a history of trying to differentiate the emotion "love" Whether Romantic or Platonic, especially with Miki remember that she's the one that told Himari what her interpretation of love is, and made Himari ask those...
Yori's more of a coomer in this than the anime hey? And also hate that the anime cut this bit out, such a good development for yori and himari as a couple.
