somehow you find this person very annoying. It's as if he is always present in the midst of your daily life.

it's all because of your father. You know that your father is an office worker, and of course he has many friends. But, this is the closest to him. You often know this man as Hiro. Even though he was a junior at your father's company, it turned out that he joined a secret state organization that included the military field. Then what does it have to do with you? indirectly, you sometimes get involved in his tasks. You even join his unit, just as a ghost member. Ghost members are usually members who are involved in certain missions, and not missions that directly refer to the community.

.... that afternoon, you had just come home from a mission with Hiro. You are very tired and sleepy, lurking for hours and constantly raising your guard. you finally arrive at the train station. Hiro sits on your right, while on your left is a male office worker.
