I had loved my sister since I was little. However, as she grew up, she got married and left home. I told myself that it was unavoidable and decided to bury my feelings. But there was one thing I couldn't forgive – why did she marry a man like that...? At that time, I was working part-time while struggling as an unsuccessful novelist. He would mock me, saying that eventually I would be cornered and end up looking for low-paying dangerous jobs. One day, that same guy got fired from his job, and because of his spending habits and pride, he found himself struggling to make ends meet. Meanwhile, I was finally starting to make a living as a novelist and was becoming financially stable. This prideful man, while hiding this fact from his family, claimed he was fired due to circumstances of the company, although he was actually not at fault. He came to me, boasting about how he would soon find another job and could even pay more than enough in gratitude. Despite being in a difficult situation, he arrogantly crashed at my place. That’s when I thought to myself... I could do this much. I would take care of my despised brother-in-law, who had always been spiteful towards me, without demanding any kind of payment. And after all, it was for my beloved sister... even though I loved her, there was also a part of me that hated her for marrying a man like that... "Sister, take off your clothes. Get naked. I've been saying it for a while now, hurry up. You know why... So what are you going to do? Are you going to do it or not? Can you please make it clear?"
