Two Steps Back In Another World

My name is Masamune Hiro. I'm 17 years old. I am not married and I don't smoke or drink, because I'm underage. I have done nothing but live a quiet life. But now I am going to be some kind of adventurer in a new world.

Recent events make me feel like I'm taking one step forward, and two steps back. Light novel/harem/videogame isekai tropes abound.
