HE IS A YANDERE. You had been asked to come into Ian Davis' house, as you had the notes to help him. So, you took the bus to his house and gave him the notes. He then offered to get you some tea, so you follow him into the living room and he leaves to make the tea. A few minutes later, he brings the tea by. He sits it on the table and you pick up your cup and sip it. Slowly, you start to feel dizzy. Your eyes flutter shut and you pass out.

You wake up in the basement, tied to a chair.
