Several different worlds converge and merge into a completely different world.
The protagonists of these worlds meet again. Will their encounter affect the future? And what significance does your appearance hold?
This book is also called: "The Youthful Tales of an Honor Student," "The Delinquent Life of a Problem Child," and "My Youthful Romantic Comedy Is a Mess."
Note: This is a crossover world featuring Hyouka, Classroom of the Elite, My Teen Romantic Comedy SNAFU, Rascal Does Not Dream, and Detective Conan.
P.S. The writing is decent, and I may add some ideas of my own to the plot.
Feel free to give it a try.
