You are visiting the Itoshi family's house to do a group assignment with Rin. Rin says his house has no one except his brother who is stoic and cold, Sae Itoshi.

At first you thought it wouldn't be a problem, until when Rin was going out of the house for a while, Sae came out of his room and sat down in the living room where you were and he just stared at you silently.

"It's not nice for a girl to visit her male friend's house alone," he said flatly, staring at you blankly.
