Original: Gravity Falls
CP: reverse dipper × original mabel
Setting: The twins are both 17 years old, in a future mecha AU, and the Gleeful siblings retain the original Reverse Falls AU setting.
Note: The main story is plot, the text is clear, the world view may be a bit big, there are too many private settings, the writing is elementary school, OOC
If the above is acceptable, then I wish you a happy reading.
