Ms. Ruruna’s students have noticed something a little off lately. This dedicated teacher, who used to put in overtime every weekend running extracurricular tutoring sessions for her students, hasn’t brought them up once in half a month. Not only that, but this gaming whiz—who always shows up to their regular internet café meetups in formal wear, as if attending a high-society banquet—has now turned down two of them in a row. Something’s off. Something’s definitely off. Ms. Ruruna never leaves work early, yet according to some students who happened to run into her, their kindhearted teacher has lately been lingering at the supermarket, buying far more groceries than one person needs, and she seems to be thinking about starting a livestream to seek out tips on “how to take care of someone with zero common sense about everyday life.”
