In Haruki Murakami's book "Yesterday," the narrator reflects on his experiences at the age of twenty, highlighting deep feelings of solitude and loneliness. He recalls a time when he didn't have a romantic partner or close friends to confide in, which left him feeling isolated. His days lacked direction, and he struggled to envision a future for himself.

The narration emphasizes a profound sense of being withdrawn from the world, often choosing to retreat within himself for long stretches without any social interaction. This introspection paints a vivid picture of youth marked by emotional turmoil and a search for connection, resonating with anyone who has felt lost in their early years.
