Reverse: 1999: I'm Ms. Z's Adopted Son

(Just writing for fun) [One heroine + rescue story + invincible protagonist + a little sweetness + mystery] (The earlier chapters aren't very good, so you might as well start at Chapter 27.) This is a world where arcanists and ordinary people live together. They struggle against each other yet coexist, having endured long years of prejudice and war. Just as people believe they're finally about to enter an era of relative civilization and peace... The world plays another cruel joke on them: the wheels of time have actually begun turning backward? Look, there's still so much of our past to choose from. Pick whatever you like... if you can make it to the end. Every era has its own distinct character. Whether you're a nobody or a world-renowned figure, the waves of your era sweep you along, driving you forward without pause. Like a curse, they stain everyone who lives through them with their own unique colors: the “disease of the age.” People long for the future because, however hard their own lives may be, they believe they can place their hopes in it. But then the “Storm” arrived... The future abandoned us. Some people went mad, some spent every day drowning in grief, and most were still swept along, powerless to resist. Of course, there were also those children. Burdened with cruel fates, they raised hands stained with blood and tears, striving to create a sanctuary for the souls cursed by their age, souls that wailed without end: a place free from discrimination, prejudice, hierarchy, sorrow, and pain. “To hell with all those self-important idiots! We have a world of our own!”
