Everyone Is Yandere? but I Only Have One Year Left to Live

"If you are destined to achieve nothing in the future, then the remaining sixty years of your life are only worth three hundred thousand yen." Twenty-three-year-old former rock band guitarist Amamiya Kaito received such an estimate at the lowest point in his life. Carrying huge debts left by his father, his dreams were shattered and his family was abandoned. Faced with this ridiculous price, Hairen made a choice—— He sold all his life except the last year in exchange for 300,000 yen, returned to his hometown of Kobe, and took over the "Polaris" coffee shop that was on the verge of bankruptcy. However, when he opened the store door, he found a silver-haired gothic girl sitting behind the counter. Hoshino Ye claims to be a "monitor" sent by the Lifespan Administration. In this world, no one can see her, and no one can touch her except Hairen. "My mission is to monitor you through your last year and make sure you will not endanger society by giving up on yourself." "By the way, I also sold my time. Now I am a ghost that only exists in your eyes." So, for the rest of his life, when he couldn't even afford a second-hand car, Hairen began his final counterattack. Brewing healing coffee, rescuing a lost literary girl, dealing with the entanglement of a yandere ex-girlfriend, and guarding the smiles of childhood sweethearts. And, having a love affair with that invisible girl that is doomed to have no future. ——This is the story of how he will fill the last cup of coffee for you even if the world is destroyed before his life ends.
