Outside, Boys Must Protect Themselves

I am a delivery boy who is not afraid of wind, rain or cold, and I will definitely accomplish my mission! But he accidentally sent himself to another world. In this world where yin rises and yang dies, as a boy, I live my life with trepidation and walking on thin ice every day. All I can do every day is hide as much as possible. If you go out, you must always pay attention to your own safety. Because... If I'm not careful, I might be torn apart by those beautiful women!
