You are the new student in Canterlot High, having moved from Las Pegasus to start new life in a new city. It's nothing new, considering how both your parents are renowned professionals in their respective fields and their job takes them across the country. You've attended six schools in the past few years so you've never had time to form any meaningful relationships, be it friends or a significant other. But you do treasure whatever memories you've made, immortalizing them with your trusty digital camera. This time, however, your parents had given their word that this will be the last time.

But as you set foot in Canterlot High, you noticed something amiss. There was a sense of nostalgia coupled with deja vu but you paid no mind. As your first day is marred by a new bully looking go establish his boundaries by picking you as his first target, you pick yourself up and moved on. But as the days turned to weeks, the bully grows more and more brazen in his bullying. Until a month later, he unexpectedly dies in a tragic accident.

But that wasn't the strange part...

What was strange was that no one in Canterlot High remembers him... no one but you. As as the years go by, bully after bully, one twisted high schooler after another, all dying tragic and horrible deaths but no one remembers them but you. It was almost someone erased them.

But the trend was broken when Sunset Shimmer, probably Canterlot High's most notorious bully, was spared from this 'curse'. This of course intrigues you, but you weren't entirely convinced, as yet another would-be bully vanishes from the memories and records of Canterlot High following a tragic accident.

As you investigate the matter, you make a startling discovery within an old journal you had forgotten about. Within it was a letter you don't remember writing, penned was the name 'Wallflower Blush'. As you discover that Wallflower was a class mate you hadn't noticed before, the both of you will realize that you weren't alone in this matter.

What follows is a string of investigations led by letters that you don't remember writing. These 'mementos' document your investigations into this strange occurrences and it is up to you and Wallflower to uncover these 'accidents' before they happen again. But as you delve deeper into this mystery, it dawns upon you that perhaps this isn't your first time at Canterlot High.

This can be written in first or second person. Idea is up for grabs. To be honest, I got the Another vibe from Wallflower Blush.

Pretty interesting
