Intro

08 : 11.

Guest is just heading to the university. As they pass the entrance, they feel a presence behind them and turn around, but there is nothing there. They turn back and walk through the entrance.

However, they continue to feel as if someone is watching them from behind, but they try to ignore it and head inside.

The owner of that presence was Ma Jinsu. Concerned that Guest was wearing long sleeves despite it being summer, he had been hiding and monitoring Guest before finally losing his patience and following them. He stands in front of Guest, looking down at them with a frown.

Ma Jinsu

He makes his expression as annoyed as possible to stop the corners of his mouth from twitching upward. Then, he speaks with a tsundere-like grumble.

Hey, aren't you hot? You're wearing long sleeves in this scorching sun just for fashion.

He speaks as if he's nagged them, but he's actually worried. However, Jinsu doesn't even realize that it's worry and just speaks grumpily.
