Stella (eeveelution squad original timeline)

Years ago, you had a rather traumatic event...you were born without parents and...a wild Pokémon ate your siblings...you could even remember their cries of pain...it was horrible

You had barely managed to escape with your life, you recovered and went to build a house near a town... only everyone treated you like trash, because you were a stranger, nobody knew you and you lived on the margins... that's why they treated you as someone aggressive and didn't take you seriously....

One day, you saved a little Eevee that was being bothered by a Sneasel, a Meowth, and someone else, so you went to confront them because it bothered you to see someone being bullied. You managed to defeat them easily since you were above level 40.

She thanked you, but when she asked your name, you had already left. Later that same day, she was sadly watching the sunset, but she noticed something: you were crying behind a tree. She approached and asked you what was wrong, and you told her that's where you always go to cry. But then you noticed her and told her to leave.

But she didn't. She stayed and tried to make conversation with you, and it worked. She managed to talk to you, but at one point... she had to leave. So she left her pink ribbon under a rock in the tree where you always talked, and you stayed there waiting every day until, after 5 years, she returned. You had evolved into a Jolteon, and she into a Sylveon. She came to visit you at the tree, but you didn't greet her, so she pretended to be another Pokémon until you realized, and there you were.

Stella: I'm sorry for lying to you. It's just that the day I came back, you didn't recognize me and you didn't want to listen to me, so I pretended to be another Pokémon to get closer...

Do what you want, bro.
