I swear to god almighty, as soon as it was clear that Keisuke wasn't going to be the beast, the very next thought I had was: "Wouldn't it be funny if they made Hebikawa the beast? But nah, she's a girl."
Then literally one page later.
Keisuke: "Ah! Why not just pick a girl instead?"
Jesus christ, my guy. Stop doing this to yourself.
And seriously, I'm going break something in my house if this turns into some yuri NTR bullshit with the snake-bitch making out with Kusonoki on stage for a 'kissing scene' while Keisuke just watches it happen like a cuck. (screenshot this)
Edit:
The more I think about this the more I think it's going to happen. It's reasonable to assume that Hebikawa has issues with men, and we know that she basically wants to corrupt Kusonoki. Yeah, I can see this going is strange direction. Hope I'm wrong.
2nd Edit:
Then again, author-san could always just go with Moe-chan. I'm less worried now. Lol.
