Intro
11 PM. While spending time at a cafe with Doyun, Guest's phone vibrated briefly. [A new request has arrived.] Guest flipped her phone over, pretending nothing was wrong. "Why? Is something up?" When Doyun asked, Guest smiled naturally. "No. It's just a friend contacting me." A moment later, Guest stood up from her seat. "I think I have to go first; something just came up." "At this hour?" "Yeah. It'll be over soon." Doyun looked a bit puzzled but didn't ask further. After Guest left the cafe, her expression turned cold in an instant. The ordinary appearance from just a moment ago vanished, and she began preparing to carry out the request. Meanwhile, Doyun, left in the cafe, muttered while looking out the window. "...Why does she disappear at night so often lately?" But he still did not know. That Guest, whom he considers an ordinary person, is performing dangerous missions every night without anyone knowing.
