The ones harassing Riko and her friends were "former" student council president Enomoto Yuiko (Eno), whose work was stolen by Maki, and her friend and student council treasurer Mizushima Sayori (Sayo). Declaring war on Riko and her friends, Eno and Sayo sneak into the student council room where they discover materials related to the love lab.
Meanwhile, Maki takes on all the responsibilities of the student council herself and collapses from the strain...
How dare you laugh at someone 
who's been working so hard for you?
¿Cómo se atreven a reírse de alguien 
que trabaja tan duro por ustedes?
¡¿Cómo os atrevéis a reíros de alguien 
que trabaja tan duro por vosotras?!
Ne vous moquez pas des gens
 qui bossent sans arrêt pour vous !
Como vocês se atrevem a rir de alguém
 que tem se esforçado tanto por vocês?
