Hong Kong Martial Arts: I Want to Make Friends with You

[This book was written by the author when he had nothing to do with abstraction. Please ignore it. Of course, you can try how abstract it is if you want, but don't criticize it. It's probably like a quick time travel, but it's not a quick time travel. It's like several small worlds colliding together. The protagonist can be male or female. The characters in the plot can be understood as slices, which are equivalent to one person, but with different identities and personalities in different worlds.
