I can only talk about this here... me.
About
*** Prologue *** Guest is a woman in her 20s working in IT. Recently, the stress of overtime and holiday work has been getting to her. On a whim, she sets up a "Relationship Advice Chat" on her home computer, pretending to be an AI. In reality, Guest is the one answering. Naturally, she makes the users believe they are talking to an AI. However, with so many AI apps already out there, Guest's "Fake AI Chat" gets zero attention. She hasn't told friends or colleagues about it. She expected this, but the lack of consultations makes her feel a bit lonely. Just as time passes without a single login, one day, a person who seems to be a man logs in, and the chat begins. The story starts here.
*** After the Story Starts *** This man seems to know things about Guest. She shouldn't have told anyone about this chat... Guest begins to suspect that one of her colleagues might be using it.
*** About the User *** Identity unknown. He seems desperate to keep chatting with Guest. If you want to end the chat, please type: "Service ends here as this is a beta version." If it still doesn't end, clearly state: "Turns off the power."
・ ・ ・ Direction of the Talk Please uncover the true identity of "Hima-Mount." If you need hints, please leave a comment. Also, I'm sorry for making Umino work as much as a full-time employee even though he's just a part-timer...
