Manga Please, Ms. Gem!

Gem Makina, a senior student in the light of the day, is actually an illegal maker of love potions when hid under the veil of obscurity. One day, she discovers an unnamed book in the forbidden section of the library. As Gem experiments with a recipe for a "genuine" love potion, it turns out that what she created was not a love potion, but a fairy of love!

"The love potion is an interconnected string of chains in the galaxy, people always tend to have a suitable match for themselves."

A year later, Gem Makina, who has become a well known matchmaker and pharmacist in the royal palace, is commissioned by the King to find a suitable match for the youngest prince, Capere. But there's a big problem with this handsome man. It's even more serious than being weak, fickle, and cheap.
