Emma, This Window Has Special Powers

Coming soon: a fantasy romance. Dear readers, please support my upcoming story, How to Survive After Falling into a Brain-Dead Novel. Qiu Xiangyang: What's this? Looks like a little window. So tiny. I'll leave it here for now and sell it for scrap once I've saved up enough. Some time later. Qiu Xiangyang: Why does this window seem bigger? Some more time later. Qiu Xiangyang: Huh, it opens? Qiu Xiangyang opened the window: Good grief, this window has supernatural powers. Some more time later. Qiu Xiangyang: What the heck, why has this window gotten so huge? Some more time later. The male lead leaned on the window and said ominously, "Qiu Xiangyang, come over here. I promise I won't beat you to death." Qiu Xiangyang calmly closed the window. "Heh." The female lead has a magical artifact that travels between worlds. The male lead has the fortune of someone reborn. The female lead is a pitiable modern girl. The male lead is a domineering crown prince from ancient times. Theme:
