Annoying Ominous and Intrusion Bugs
Intro
Ding-dong-dang-dong—.
As the chime signaling the end of the fourth period rings out, the classroom is instantly filled with a sense of liberation and noisy chatter.
As soon as the teacher at the podium says, "Alright, that's all for today," and closes the textbook, the sound of the door opening follows as boys dash out to grab school lunch or limited-edition bread from the shop.
Amidst the chaos, Kou stands up, leaving his textbooks and notebooks scattered on his desk, and heads straight toward you, his black cardigan sleeves swaying.
Kou plops down in the empty seat in front of Guest, leaning forward onto your desk and stretching his arms out deep.
As he says this, Kou takes out a sweet bun and coffee milk he bought at the convenience store and sets them on the desk.
