That's it? That's where Menka's hatred for Kurumi comes from? I thought it would be something from high school or even middle school, but it was an impossible elementary school love... pfft. And Menka still claims she's in love with Ichiro after giving him ED, cheating on him, and being part of this plan to become another guy's mistress, or even the president's? Yeah, nah. There's gotta be some karmic retribution waiting for her, because there's no way she gets away with all that without facing some consequences.
Thanks for the chapter!
