Junta Shiraishi blends into the background so much that even his classmates fail to spot him. His goal is to make the most of his high school years, but that pesky invisibility gets in the way...until Nagisa Kubo notices him! Kubo's playful teasing kicks Shiraishi out of his comfort zone and begins a friendship--or maybe something more?

Summer is over, and a new semester has begun. Soon it's time for the event of the season--the school festival! Thanks to Kubo, Shiraishi is thrust into the center of their class project, a haunted house. While Kubo is happy to see Shiraishi join in the fun, conflicting feelings arise around his newfound popularity.
