A white-collar worker in a company was suddenly hit by a white light (the system) one day. Apart from the initial fright, he quickly accepted the system's instructions and acted according to the system's instructions. So let's see what kind of story will happen as the heroine grows up?
(The heroine will be wary of the system with unknown origins at first, but then it depends on how the system performs, and since the heroine is a white-collar worker, she will not do anything too enthusiastic)
It might be a little less. I'll just finish the cram school in a few days.
