In today's science class, the four girls learn about the 'green bug' which is known as euglena. Brimming with scientific curiousity, Jun can't stop wondering about what that might taste like, and agrees to go have euglena ramen with Koizumi-san. What is that absolutely foreign flavor going to be like???
Oh, man, how embarrassing! 
You heard the whole thing!
!كلاّ، كم هذا محرج
Oh Gott, das ist mir peinlich!
Du hast alles mit angehört!
¡Qué vergüenza!
¡Qué vergüenza!
Aaah! Che imbarazzo! Mi ha sentito!
Ah, que vergonha!
Ох, стыдоба-то какая!
