The two classmates were just randomly talking about their classmates, and realized it? Now that's lampshade hanging.
Wow Akira, you're that inncoent? Come on, I would have thought a gal like you would know what Shigure was doing. Seems Shigure is really need for Kotaro. Compared to Kanae, who's pretty straightforward, Shigure's gonna have a hard time getting to Kotaro.
I find it kinda funny that both Kanae and Akira tried changing their outfits to seduce Kotaro, but Shigure really was just worried. That's best girl behavior right there!
