Plot Summary

Felicita loves her new hairpin
When Libertà mentions how it would be sad if Felicità forgot them, Nova remarks how she is irreplaceable. Felicità watches the two from above, and when Luca comes in, she asks Luca what is love. Luca freaks out in confusion. Meanwhile, the maids are looking at the meals that they cooked for Felicità's recovery celebration. Elsewhere, Jolly talks with Felicità and how Mondo could fall into a coma again. Felicità informs Jolly that her Gil Amanti can negate her Wheel of Fortune's side effect if she can complete the love. Jolly finds this predicament amusing, and he tells her to choose between Libertà and Nova. Afterwards, Libertà and Nova find Felicità all sad, and they take her out on a cruise. Nova presents their gift to Felicità, a butterfly pin.

Liberta waits for help
After a montage of fishing, the two boys find Felicità all tucked out. Libertà shares his past with Nova, and Nova asks what he will do if he is confident in himself. Then, storm clouds suddenly appear, and Felicità wakes up. With the boat rocking, her hair pin falls off, and Felcità goes after it. She falls into the sea, and both Nova and Libertà rescue her. They swim to an island, and inside of a cave, Nova feels Felicità is cold. Libertà volunteers to start the fire because he wants the two to believe in him. Inside, Gil Amanti speaks to Felicità about the two boys, and she wakes up to find Nova at her side. Back at the manor, Dante scolds them for being irresponsible. Nova apologizes and tells him how Libertà save her. Dante remarks how Nova is mature now. Outside, Nova tells Libertà that he is going to wake up up his parents, and why he lost control over his powers. Libertà refuses to believe that Nova does not care for his parents, and he punches Nova for not opening. He asks Nova to allow him to help, and Felicità offers her help.

The two find Felicita fast asleep
In the library, the three research on Arcana Powers, and when Libertà brings up how Nova's powers did not permanently put the pirates to sleep, Jolly appears. Jolly gives Nova the answers on how to wake up his parents. Nova leads his group to his parents' location. Though, Nova learns the consequence of his powers, and if he does wake up his parents, he might might fall into slumber. Once Nova uses his Arcana Powers, he struggles and then falls unconscious. He remember the good times with his parents. Afterwards, he wakes up to see Felicità and Libertà who points to his parents who are still sleeping. Libertà states that they should wait til morning. The three of them share a blanket, and both Nova and Libertà thank each other. Felicità wonders what love is, and she falls asleep quickly.
Next day, Jolly informs Mondo about Nova's parents' status and how Nova's regret still holds him back. As Mondo states that the Arcana Duello is tomorrow, everyone prepares for the duel by checking their weapons or do some training.
