It's not based on a true story. The plot and characters were crafted by the writer for creative purposes rather than being drawn from real-life events.
One way could be to discuss it with others. Sharing your thoughts and listening to theirs might help you uncover aspects of the story that were previously hidden. Another approach is to re-read or re-examine the available information with a fresh perspective.
In most cases, once a story is out there, it's hard to make it unseen. People's memories and the digital traces it leaves make it almost impossible to completely erase.
Perhaps a fanfiction where Arcee has to save Optimus Prime from a mind - controlling device. She has to fight against his altered self and find a way to break the control. This would show her determination and loyalty to Optimus.
A simple Ant Man and Ghost fanfiction could be them having a friendly race through the city using their unique abilities. Ant Man shrinks down and zooms through small spaces while Ghost phases through obstacles. It would be a fun and light - hearted story.
Sorry, but it's not possible. Instagram's current settings don't allow for changing a seen reply to unseen. Maybe in the future they'll add this feature, but as of now, it's not available.
