[Kuroko's Basketball + Brothers Conflict] On the Compatibility of Split Personalities and Big Brothers

In front of others, Ri Xiang Jue has always been the gentle, considerate big brother to his little sister, Ri Xiang Huima. But in truth, this big brother is twisted to the core, a split-personality yandere. Everyone is stunned! Ri Xiang Jue, flashing a bright smile: "Good day, classmates. It's another lovely, sun-shining day, isn't it?" People who are good at acting often lose themselves, because they've worn their masks for too long. Ri Xiang Jue is the perfect example. If you can't understand the joys and sorrows of ordinary people, then imitate them! Disguise yourself as normal, blend into the crowd, and live a lonely, bewildered life, until you're saved by a girl named Ri Xiang Huima. So even if it takes everything he has, Ri Xiang Jue will protect Ri Xiang Huima! But in the process of protecting her, some strange people seem to be coming over of their own accord. This story focuses on the male lead being pursued. The ending is undecided for now. I'm a beginner writer, so the prose might be awful (too painful to look at). I'll try to avoid making it too wish-fulfillment or melodramatic, but I don't think that's possible... The male lead is somewhat normal at first, but later his whole personality splits apart. At first, he's a perfect, perverted sister-complex, and later he evolves into a yandere, crazed with a brother-complex (not Asahina Juushimatsu). Anyway, this is a practice story to satisfy all of Cat-chan's weird tastes. If that's not your thing, please head out through the upper-right corner! This is Cat-chan, who's easy to approach and easy to win over. Of course, you can also call me Shameless Cat-chan
