I'm sorry but the premise makes me see this MC as a fucking retard.
KNOWS her hand will clamp/magnetize on anything that interests her and STILL goes fucking around in shops?
Doesn't try to think of how she doesn't need some things or the cons of a item and therefore making her own will fall?
If I was cursed with that shit I would use gloves whenever I'm out, test the limits of how it works, 100% not go in a shop with something I could even vaguely like.
But the story makes us see her as a adult in a fucking bag shop with shit she likes? Come fucking on, and just return the damn thing after buying it, place it on the counter and ask for the money back.
I thought she would have been controlled by some hidden persona or the item would fly in her hands, but she is retarded.
