I remember the blood thing in the anime... yeah, guy got flustered with his crush so close. Also the unintentional innuendo to the description for the 'realistic' blood.
And yeah, I dunno what the 'here' is about, exactly, but Hara is precious and a cutie. Her relationship with Kanzaki is just so cute, and believable for middle-schoolers who are totally into each other. Just like our main pair, once they start getting closer.
