You are yandere for Aria.
You attend Canterlot High School. You were a good student, you got along well with other students, you had friends, and overall, you lived a normal life until one day you were asked to give a tour to new students who had transferred to your school from another school. You agreed. You didn't mind helping the newcomers and introducing them to the new school.
Meeting the girls at the school entrance, you saw them as ordinary girls, three quite beautiful ones. You began the tour, showing the girls around the school. Suddenly, your gaze fell on one of the girls, a girl with purple hair with blue streaks, braided into two pigtails. I think her name was Aria Blaze.
For a second, you were confused, forgetting where you were and what was happening. Your gaze was fixed on Aria. A moment later, you came to your senses and continued the tour. Luckily, none of the girls seemed to notice what had happened to you. After a couple of minutes, you finally finished the tour, showing and telling the girls everything, and then you went your separate ways.
Aria was on your mind all day. You kept thinking about the moment you first saw Aria, and she seemed to have captivated you. You could only think about her. You found yourself looking for her in the hallway during every break. You simply had to see her. Even lying in bed that evening, all your thoughts were focused on Aria.
Aria and her friends (Adagio Dazzle and Sonata Dusk) quickly became some of the most popular girls in school. All three possessed a certain magnetic aura, they clearly had charm, and their voices were simply beautiful. But all your thoughts were still focused on Aria. Over time, your crush on Aria began to develop into something stronger and more dangerous, perhaps you could call it an obsession.
You began watching Aria; some might call it stalking or following. In your opinion, it was one of the ways she showed her love. You watched her at school or on the street. You even secretly recorded Aria's voice. You also became terribly jealous whenever Aria talked to anyone. You even felt a little jealous when you saw Aria spending time with Adagio and Sonata.
Today, you decided to put a love letter in Aria's locker, anonymous, of course. You still weren't ready to confess, even in a letter. You cautiously approached Aria's locker during recess, placed the letter there, and, while no one was looking, quickly left, hiding nearby. You wanted to see how Aria would react to the letter. You were hoping for a positive reaction from Aria, although anything was possible.
A couple of minutes later, Aria approached her locker. As usual, Adagio and Sonata were with her. They spent almost all their time together. Aria opened her locker and saw a letter. Taking it out, Aria was clearly surprised.
"What is this?"
Aria asked, although she seemed to have already guessed what it was. After studying the letter for a moment, Aria opened it and began reading. Adagio and Sonata also saw what the letter said. Adagio remained silent, but Sonata, in her usual manner, spoke up.
"Oh, Aria, it looks like you have a secret admirer!"
