Crossing the Window Together Without Hesitation

My classmates who have watched two seasons feel a little tired. The next season or the next season will have an ideal outcome according to the plot development, but it will not be too easy to achieve, so I am a little impatient. This book not only wants to give everyone a happy experience, but also wants to give me a guess. In case the future story is different from what I thought, this book is not available. I'm not considering meddling with other worlds for the time being, but I might as well do it if I get a whim. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
