manhwa name

im trying to find this manhwa pls help me
ok basically the fl ( i don’t remember if she’s a child or not) thought that she does not possess any magic powers but she in some way was captured by some guys and they i think put her in a cell with a beast man (to make him eat her basically) but he doesn’t and she promises that she will free him so she escaped through the ceiling, after days she rescue him and she said this phrase “you’re safe now” and ALSO she realized that she actually has magic powers cuz she opened the cell’s door which is casted with a magic spell so it was basically impossible to open it, then i also remember she frees other beastman and also there was another character with her and he could fly??? maybe using his powers
