"I Sold My Life for Ten Thousand Yen per Year." was a manga I was putting in the back of my head for a while in my "reading list". But once I decided to read it, I found that it was adapted from this, Three Days of Happiness. So, I bought the novel and I read it first. I went in with high expectations and prepared myself to be depressed after. But my expectations were shattered. This was so heartbreaking and depressing and yet it's so warming and fulfilling. I can't put all the emotions I'm feeling into words, but I feel empty and fullat the same time after finishing this novel. I love this so much <3, planning to read manga adaptation soon too. 100% recommend, one of my favorites now.
