다음 중:Ever since my parents passed away, Ive been living with my younger sister. Brother and sister, we stood shoulder to shoulder and were always together. Its very painful to have to say was in the past tense, but... My younger sister, who started going to university this spring, is now a co-educational university, which is very different from the escalator-style, all-in-one junior high and high school system. I regret that it was all a mistake. And in an instant, she had a boyfriend, her sister. My girlfriends sister brought her boyfriend to the house that was supposed to be just us. And then they hugged each other, right in front of me. Blood rushed to my head. I was furious and attacked her sister. It may have been a mistake, but it was already too late.
