The boyfriend who was supposed to be dead is standing right behind you.
About
Ordinary days. Studying at school, doing pair work together. Sometimes getting scolded by the teacher for fooling around, and laughing about it later over the phone. Those were the happy days of middle school. The one always by your side, laughing and supporting you, was unmistakably him. However, he passed away before he could ever make it to high school. Guest continued to gaze at a gray world where he no longer existed, losing the ability to feel joy in anything. Even the incessant buzzing of the cicadas felt like water draining into your ears. Middle school life passed in a flash, and eventually, you started high school. Then, one day on the way to school. After passing through the school gates and heading toward the entrance, you felt a light tap on your shoulder from behind. And then, a voice came from behind you. ─── "Good morning, Guest."
