I'd really recommend it since it's a short read, (the manga only has 18 chapters). It's definitely the most brutal piece of media I've read mostly due to how it closely represents a lot of us disenfranchised individuals that have no respite from their suffering, the MC doesn't have money, nor a job, nor a girlfriend, nor a true friend, nor even a family that wishes to see him, it's very clear early on that he is rotting away like many of us here so he decides to sell his lifespan in a bid to neet out for just a period of three months. It's true he's a failed normie, sure, but the pain is still there as he doesn't have anything good to remember his life by. The story has many interpretations since him selling his lifespan could be a potential metaphor.
