There’s no formula or manual that can help you tie a man down. And perhaps there’s no souvenir that can imprint someone’s memory on your subconscious mind forever.
But this woman whose identity we don’t know has come up with something that can help her just do that. How? By wearing a necklace which contains the sperms of her man.
It sounds weird but that’s her own way of showing how this guy means to her and etching his presence in her memory forever.
