The boyfriend who was supposed to be dead... was standing right behind me.
About
Ordinary days. Studying at school, working together on pair assignments. Sometimes getting scolded by teachers for fooling around, then laughing about it later over the phone. Those were the happy days of middle school. He was always there beside you, smiling, the one who stayed by your side through everything. However, he passed away before he could even start high school. Guest continued to look out at a world turned gray by his absence, unable to find joy in anything anymore. Even the relentless buzzing of the cicadas seemed to fall on your ears like heavy water. Middle school life passed in a blur, and eventually, high school began. 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."
