It is summer vacation and our three heroines are sleeping over at Momoko's house. Yuri then asks about Momoko's ring and then, Yuri and Hinagiku start teasing her since she has no boyfriend yet. Then, they called a radio station to request a song. Noise appears in front of building where the radio station is located then goes in, because she feels something. A girl DJ reads a letter. It is about M who falls for K but her love is slowly focusing on another person Y. Momoko thinks that it is very much like her situation as her ring glows and somehow, the letter also glows.
The DJ continues to read the letter as Noise goes into the studio and makes the people sleep by blowing at them. Hinagiku and Yuri ask Momoko if she sent the letter and Momoko denies it. In his house, Yousuke is also listening to the radio, too and wonders if it is him being talked about. In a glass on the table, in it, there is a small bell and it starts glowing and rings. Noise takes the letter from the frozen DJ and reads out loud that it is a letter from Momoko and that she is beginning to fall for Yousuke. Momoko blushes as Yuri and Hinagiku are surprised that it is really from Momoko. Momoko just tells them that it is time to sleep and immediately turns off the radio.
The letter then stops glowing which surprises Noise. Momoko hopes that Yousuke is not listening to the radio station. Yousuke lies on the sofa, thinking about the bell that is ringing a while ago. Noise reports to Sandora that the letter has lots of love and a special power in it. It might be that the Something Four is with the girl who wrote the letter. Noise leaves as she tries to find the boy whom a certain Momoko likes.
In the park, Momoko and Yousuke meet. Momoko denies about the letter as Yousuke tells her that he did not believe it either because he knows the she does not like him. Momoko feels sad since she knows that she is lying. Noise is watching them. As they separate, Noise grabs on to Yousuke who is puzzled, asking who she is. As he struggles for her to let go of him, Noise hypnotizes him and goes with him to his house. Momoko sees all this and is angry while wondering who the girl is. Jamapi asks her if Yousuke likes older girls as Momoko tries to push him back into her bag.
In Yousuke's apartment, Noise finds out that Yousuke lives alone like her and tells him to obey her as they determine what to do since Momoko is near. Momoko standing outside Yousuke's apartment, wonders what the two are doing since they are in there for half hour already. Momoko's ring then glows resonating with Yousuke's bell which glows and rings. Noise takes the bell, thinking it is the Something Four, as Yousuke tries to get it back, saying that it is from his father. Noise says that she will change it then gives Yousuke an electric shock, making him unconscious as she leaves with the bell. Momoko rings the doorbell and finds the door open. She goes in and finds Yousuke unconscious on the floor.
Noise shows the bell to Sandora. Sandora leaves Noise when he finds out that it is not the Something Four when the bell gets a crack from Sandora's test. Noise is sad that Sandora left her so she swears revenge on Yousuke. Meanwhile, Momoko wakes Yousuke up and asks him about the girl with him. Yousuke cannot remember the girl but he did remember his bell being taken. Yousuke is a bit confused, what to do, that he snaps at Momoko. Then, he apologizes, saying that the bell is given by his father as a lucky charm. A flashback of Yousuke's father giving him the bell and left, never to be seen again. His mother lives in Paris. Momoko realizes that Yousuke lives alone. Yousuke says that he cannot live Japan because he loves it where he had lots of happy memories. Momoko agrees with him.
Suddenly, Noise enters the room, accusing Yousuke of tricking her - the bell. Noise pushes Momoko out the room which knocks her out. Noise closes the door and throws the bell on the floor. Yousuke immediately grabs the bell. Noise creates a large bee/wasp monster to push Yousuke to the wall which is absorbing him. Momoko regains consciousness as Jamapi goes out to call the others. Momoko transforms to Wedding Peach and goes in the room to help Yousuke. The bee tries to attack her but she destroys it. Noise pins Wedding Peach down with large spikes. Noise is glad for Sandora will forgive her if she capture and destroys Wedding Peach. Noise starts hurting Wedding Peach and Yousuke who is trapped on the wall, sees Wedding Peach then she looks like Momoko. Yousuke tells her to be strong then the bell glows.
Suddenly, they are all covered with a bright light. Wedding Peach and Noise is surprised. Momoko's ring and Yousuke's bell join together and it flashes. A box appears and opens, revealing a Something Four, a heart-shaped ring with a new crystal wand. Wedding Peach uses the wand to absorb Noise attack and sends Noise to happy land, thanking Wedding Peach. Wedding Peach and the recently arrived Angel Lily and Angel Daisy are surprised with the power of the Something Four. Wedding Peach goes to the unconscious Yousuke. She puts the bell in Yousuke's hand and thanks him for his help. On their way home, Yuri and Hinagiku teases Momoko as to what she and Yousuke are doing together as Momoko denies that there is something between them.
