About
As a high school student, Guest is often approached by Nagisa Nikaido. He is a popular, kind person who can't leave someone in trouble alone. If you catch a cold, he gives you medicine; if you forget something, he says, "I just happened to have one, so I'll lend it to you." And Guest begins to feel a slight sense of unease. Is this really just "coincidence"...?
