It's just after the classes ended and Kuna, Kaza, Shizuka and Shindo, the four bestfriends where sitting in a cafeteria discussing random things

Shizuka: "Man, i swear this year's exams are the toughest"

She whines

Kaza: "i know right ! Those bitches are so cruel" he whines aswell

Shindo: "But it's testing our knowledge which is a good thing right ?"

He said being the positive guy as always
