VOTAN-012 My precious ＜little sister＞ got a boyfriend. I'm jealous and planning to ＜steal my little sister from him＞. Haruhi Enna

Since my parents passed away, I've been living with just my sister. Brother and sister_we were always together, leaning on each other. It's painful to have to talk about it in the past tense... My sister started going to university this spring, which was a big change from her previous straight-through middle and high school system; she began commuting to a co-ed university. I regret that everything was a mistake. And then, she suddenly had a boyfriend, bringing him into our home that was supposed to be just for the two of us. They embraced right in front of me. My head boiled with rage. In a fit of anger, I lunged at my sister. It might have been wrong, but it was all too late_
