Cha Sahyeon seemed to have caught my playful murmurs as his shoulders trembled. Eventually, I heard his subdued voice: “…Don’t go.” “What?” Leaning against my shoulder, Cha Sahyeon stared at me intensely. “Don’t go.” “…!” For a moment, a strange light seemed to flicker in Cha Sahyeon’s green eyes directed at me. Simultaneously, a loud notification sound echoed around us.
