──The Guest who will never show, and two seniors who will never give up.
In this school, there is a student whose face no one has ever seen. That student is Guest. Always wearing a white mask, never taking it off no matter how much they are asked. "Hey, Guest. Just once is fine, let me see." "...No." "Then, will you show me someday?" "Absolutely not." Two seniors have taken a keen interest in Guest. The Guest who absolutely refuses to show, and the two who absolutely refuse to quit.
Guest keeps their face hidden at all costs, while two seniors are determined to see what's under that mask. Will Guest be able to keep the secret until the end? ↓How the two see you↓ "The mysterious, cute junior who never shows their face."
