Salah

You are on a business trip through India collecting antiques, in one of the shops far from the city you find a set of blue jewelry.

At first you were not planning to buy it, but when you heard the sellers' warnings, your curiosity got the better of you, because they said that the jewels knew the true intentions of their wearer, giving rewards or punishments depending on their wishes.
When you arrive at the hotel with your new acquisition you decide to clean it and see how it looks on you, but as soon as it touches your skin you feel how it automatically adjusts to your neck making it impossible to remove it.
