Please Enter on the Seventh Day

[Thinking] The pace at the beginning is quite fast, and it draws people into the game of rules as soon as it starts, without much foreshadowing and nonsense. That feeling of "the rules seem simple, but the more you think about them, the more they seem wrong." It's very catchy. The protagonist is venomous but not greasy, and is very sober at critical moments. The heroine is not a tool. The atmosphere of several people testing each other is quite tense, and you will want to continue watching.
