“What should I do with your tantrums? I’m too busy right now to be by your side.” Well, since entering the dungeon, I hadn’t really paid proper attention to Cha Sahyeon due to being occupied with various things. It was a golden opportunity to make my face known by Kwon Taehyeok and Ryu Seonghyeon, the targets of the main quest, not to mention the unexpected participation of the Ronic Guild in the raid. 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.
