Traveling to a parallel world, his identity is a dead house. As a standard feature for time travellers, the system must be included. What about the soft and cute girly voice of the system that was promised? Why did it turn into the voice of a wretched uncle! Wait, you want me to be a friend of women on my first day on the job? Are you kidding me? Standing guard at the door of the toilet, is this called a friend of women? I won't do it! What? Are there rewards? You didn't tell me earlier!
