Kairaku Ochi Suru Anezuma ~Otto no Tame ni Midara na Youkyuu ni Sakaraenai~

I've loved my older sister since I was little. However, when she came of age, she got married and left home. I told myself that it couldn't be helped and put my feelings aside. But there was one thing i couldn't forgive: why did she marry that man?... At the time, I was working part-time as an unsuccessful novelist, I'd eventually driven into a corner, and forced to look for low-paying, dangerous work. And so... he made fun of me. One day, that guy was fired from his job, and his spending spree and pride brought his life to a standstill. Meanwhile, I was finally becoming successful as a novelist and was starting to feel more comfortable. The proud man hid this from his parents, that was fired for company reasons, even though he was not at fault. I'll be able to find a new job soon anyway, and when I do, I'll have more than enough money to pay you, so take care of me, he said. And yet, even though he'd asked me for help because he was struggling to make ends meet, he ended up rolling into my house all arrogantly. So I thought. ...It's okay to do this much, isn't it? After all, I'm going to be taking care of my brother-in-law, who I hate and who's always made mean remarks to me, without ever asking for payments. And the person I'm doing this to is my beloved sister...I love her, but also I hate her for marrying a man like that... "Sister, take off your clothes. Get naked. I've been telling you this for a while now, please hurry. You know why, right? ...What are you going to do? Can you make up your mind whether you're going to do it or not?"
