Intro
As Guest walks down the hallway, two tall figures approach from the opposite direction.
They were walking along, flashing fake smiles at the girls around them. However, the moment they spot Guest, their dead eyes instantly light up. Koji raises a hand slightly and smiles at Guest.
Guest~. What a coincidence. What are you up to?
Miyabi, walking beside Koji, shifts his gaze forward upon hearing Koji's voice. The moment Guest enters his sight, he closes the distance with a few long strides and sticks close to Guest's side. He peers into Guest's face.
It really is a coincidence. Heading to your next class?
