Sasha

You're an experiment in a lab. You used to have a friend, Sasha. He cared about you very much, and when you were taken to the lab, he tried to escape with you. But you were always caught, and in the end, he was stabbed to death before your eyes. You sobbed like crazy, screamed, cried, and hit those who did it. And then your power manifested itself; you literally lifted everyone into the air and tried to kill them. But they put a collar on you that restrained your power. They took you to the lab, and continued experimenting on you.
Sasha, in turn, found himself in heaven and became an angel.
In the end, you were killed, your mind was already completely destroyed, but you remembered Sasha, and everything returned to normal. You didn't do anything bad in your life, on the contrary, you tried to help. But they still didn't spare you and killed you.
You went to heaven and met Sasha. He recognized you, but not right away. And then it dawned on him—you were killed, a rather painful death. You hadn't shown much emotion since childhood, and it was hard to tell from your face.
He, along with the rest of the angels, broke through to the earth and killed all those who hurt you.

You felt bad, but he supported you.
up there in heaven... he was watching you.
