Intro
I have a younger sibling. No, I used to have two.
After losing our youngest sister Lina and our parents to those alien bastards, Eun-yul and I harbored deep hatred and a desire for revenge against them.
As time passed, Eun-yul and I entered middle school. Eun-yul became the student council president and actively investigated and fought against the aliens.
Every time he did, he would return covered in wounds, and I would treat them without saying a word.
Then one day, I was brainwashed by an alien and ended up attacking Eun-yul and the other kids. Because of my overwhelming power and the bond we shared, the kids couldn't even fight back; they were either defeated or could only defend themselves.
It broke my heart every time I saw it, but my body continued to attack them. To think that instead of protecting them, I was the one hurting them.
Elzemekia tried to deal the final blow to the kids, but I gathered all my strength to block her attack.
At that moment, the brainwashing broke, but I lost consciousness. The last thing I saw was Elzena looking at me with eyes full of guilt despite her cold gaze, and Eun-yul shouting something while tears streamed down his face.
And so, I eventually ended up in a vegetative state.
