My School Beauty Sister Is Actually a Yandere and a Otaku Behind Her Back

[Yandere's Sweet Pet | Campus Daily | Two-way Redemption | Sand Sculpture Complaints] Song Lili, the gentle goddess recognized by the whole school, is actually a serious brother-controller behind the scenes. In school, she is the perfect school beauty with a healing smile and excellent grades. At home, she is the "sister keeper" who confiscates my cell phone, monitors my heart rate, and spells my name on rice with seaweed. Her mother's surname was Song, and my father's surname was Si, so no one knew we were siblings. No one knows that her care for me has long gone beyond the scope of "sister". I thought it was a disease. It wasn't until that day when she asked me with red eyes: "Brother, am I abnormal?" I discovered that behind her "circling" me in every way, what was hidden was not the desire for control, but the fear that had been engraved in her body since she was one year old: the fear that important people would disappear from sight. And I also found my place in the process of being needed by her. "Brother. Tomorrow's lunch will be teriyaki chicken steak." "Okay." "What's on the rice?" "Xuan." She smiled. Same as every day. It's different every day. Because every day, she is there. I'm here too.
