What are the general plots of Love Genie and Happy Jill?

Love Elves and Jill is a magical and girly animation.

In a magic kingdom, two sisters, Legille and Bingbing, made an appointment to sign up for the School of Magic. But Bing Bing had a stomachache that day, so she misunderstood Le Jill to hurt her on purpose. Tammy witch promised Legille to go to the earth to collect the energy of love, and then promised to let Bingbing enter the magic school. So Legille stumbled into the world with the angel of love and the box, and was mistakenly taken in by Habib's mother. During this period, a series of stories happened, and Legille made Habib, who hated him, and himself become good friends.

On the other hand, Bing Bing secretly cultivated wild magic, followed Legille to the earth, but had no intention of breaking the ice cave that sealed the demon queen. The Devil Queen used the black magic named Bing Bing as bait to stop Legille from collecting love. But in any case, Le Jier can turn the tide and collect love soon. In order to regain her freedom, the demon queen didn't let Le Jier collect enough energy to seal her again, so she used black magic to confuse Bingbing. Le Jier used all the energy collected for a long time, and Bingbing also woke up and joined forces with Le Jier to deal with the banshee, but the strength was far from enough. Just when Le Jier decided to sacrifice herself, she regained all her strength and defeated the banshee story.
