As Lia expected, after she taught the owner and the staff the recipe and they perfected it, it wasn't even a day before their new flavour became a sensation and all the people poured into the store, causing lines as long as the city to form.
The pitiful sweet store opposite to this flourishing one, that was once booming, was totally empty and over the course of a few days, people from other cities stormed towards this small store, causing the Z brothers business to look like an embarrassment.
This news instantly reached the brother's ears and they knew they had to do something about it.
Lia didn't expect things to go so smoothly, especially not for it to become such a popular sensation. All she did was to take a beloved flavour from the mortal world- matcha.
However, the camellia Sinensis plant from which green tea was made out of, that grew in the immortal world, was ten times more flavourful than the one in the mortal world, so that it almost became its own new flavour.
