rental person who does nothing: a memoir (Shoji Morimoto)

This is the memoir of a person in Japan who decided to do nothing as a career. He runs a twitter where people send him requests, like accompanying them to a new restaurant or sending them a text. Basically, he does small things for no consistent income.
Unique, right? He defines the word "nothing" throughout the book, and dives into how people have value and presence, without the need for a career, despite what the modern world says. He was yelled at by his former boss, who told him he was a 'vacancy', and basically started this whole gig to spite him. Learned a lot of interesting things, like how sometimes having a stranger to talk to may be more beneficial than a friend, who has an opinion about you.

I think it's normally reassuring in life to have particular names for relationships: friend, boyfriend/girlfriend, couple, and so on. On the other hand, once a relationship is fixed, it seems to carry restrictions and responsibilities.
