Jedite discovers that humans spend a lot of energy on love, and sends his servant Fro to take advantage of this. He starts a radio program called the Love Line (as the DJ), and reads a love letter by Miss Haruna, and offers a romantic prize to the owner of the letter that is read on the air.

At school, Miss Haruna is late for class. When she arrives, her energy has been drained by a Flower Pin she won on the Love Line. Luna encounters Andrew (whom Serena is in love with) at the arcade, and decides that the arcade should be her communications base. Serena and Molly run into Darien, who calls Serena "Meatball Head" again, and Molly thinks he's handsome, deciding to use Darien as the inspiration for her love letter application. Serena writes a love letter, but when she tries to take it to the station, a guard tells her there is no program called Love Line. Molly's letter is read on the air, and she gets a flower like Miss Haruna's, which drains her energy. When Serena gets too close to it, some of her energy is drained and she falls asleep and has a dream about Tuxedo Mask, and is about to find out his true identity when Luna wakes her up and tells her that the Negaverse is behind this. Luna gives Serena the Luna Pen, which she can use Disguise Power to disguise herself as something. She uses it to turn into a sophisticated talent agent to enter the radio station. As Jedite is hosting the Love Line, Serena talks on the radio and tells everyone of Jedite's plan, and is then attacked by the Negamonster Fro. Serena transforms into Sailor Moon and fights Fro. Eventually they get to the roof of the station, where Sailor Moon uses Moon Tiara Magic. Fro dodges it, but it comes back at her and destroys her. Sailor Moon then throws her Tiara at Jedite, but he stops it and makes it fall to the ground. As Jedite advances on Sailor Moon, Tuxedo Mask arrives, and Jedite leaves.
