**Synopsis** How did it come to this...? That day, we'd come to the research facility of Rewand Corporation—the country's biggest pharmaceutical company—on a guild master's request to help with an investigation. We were chatting and laughing in the carriage like always, heading to the job site as usual. When we arrived, someone claiming to be in charge told us, "I'll call the researcher in charge, so please wait here," and led us to a room in the facility. We waited for a while, but no one showed up. My guild companions and I grew suspicious, and when we tried to leave the room, we found it was locked. Then everything suddenly went dark, and when the lights came back on, my companions had vanished—I was all alone. Suddenly, a researcher appeared with a syringe filled with some mysterious black liquid and attacked me. I managed to escape and ran through the facility searching for my guild companions. I finally found Lloyd the paladin, but that black liquid was dripping from his eyes and mouth, and his gaze was hollow. "Paladin Lloyd: Sorry... I'm a paladin, but... I couldn't protect everyone properly... Please... just you... run away." Crying, I ran to find the others. But... "Archer Erica: Guest!! Please, run away!!" "Grand Mage Leon: Guest!! Please, at least you should escape..." "Fighter Jin: Guest!! You gotta run!!" They were all leaking that black liquid from their eyes and mouths, but somehow still standing, trying to get me to escape. "Priest Rud: Guest!! This way!!" Rud was in the same condition but somehow mustered the strength to grab my hand and pull me out of the room, running down the hallway. But a crowd of researchers and assassins chased after us. When we reached a certain room, Rud said: "If you go through that room ahead, you should be able to escape from the facility. Go, Guest." But I refused. "I'm a priest... so please, let me at least act like a priest at the end and protect you." Rud smiled sadly and pushed me into the room, closing the door. I could hear the sounds of fierce battle from beyond the door. The urge to rush back to Rud overwhelmed me, but I held it back and tried to open the exit door, carrying my companions' wishes in my heart. But... the door wouldn't open. Desperate and devastated, I collapsed to the floor, and that's when I saw a strange red glowing stone. 'Chronos Stone' For a moment, those words seemed to float before me, and then I was enveloped in brilliant light... When I came to, I was back in that room at the facility. Back to "that time" when everyone was still there...
