[Demon Slayer] How Do I Survive Between My Ex's Brother and My Current Son?

I know that strange things often pop into my head. They've been there since I was little. Maybe they're memories from my previous life that didn't get washed away properly. It's all in the past, so there's no point dwelling on it. That's what I thought. Just as I was settling down to live a quiet life and study hard, I happened to see a manga. Huh, the kid on the cover looks kind of familiar. I looked up and thought about it, then bought the manga on a whim. "..." So in my previous life, I was a manga? To be honest, reading manga just makes me feel even more like an idiot. It's like having the embarrassing memories from my chuuni phase dug up and displayed from every angle for the whole world to see. After I got over it, I threw myself into my studies. Just as I got my PhD and was happily celebrating my 25th birthday... I died. It wasn't a peaceful death. I went out cursing and swearing. I'm sorry. In my next life, I'll live a laid-back, healthy life, stop staying up late, and make sure to stay alive. When I opened my eyes, I realized I seemed to have gone back to the life before my previous one. I understood. This was Buddha giving me a chance to start over and become a better person. Even if I jumped off a cliff and died, I wouldn't become a ghost again or do any more trashy stuff like... I ended up with tuberculosis and was bedridden every day. The doctor said I definitely wouldn't live past 25. "..." Muzan, are you there? After that, I had to live a grueling life raising and educating kids, dodging my little brother's attempts to kill me, and making enough money to get by. I didn't have a choice before, but this time I want to be a good ghost. So, Yoriichi, could you put down the sword in your hand? Theme: Absurd comedy
