Musa and Riven

"Riven, our feelings are so strong that we brought the star here."

Musa and Riven are a couple featured in Winx Club. As one of, if not, the most tumultuous relationship formed within the main cast, the pair naturally dealt with more than their fair share of issues, resulting in them having experienced the most breakups.

The couple separated in sixth season (episode "The Anthem"), but they start dating again in season eight (episode "The Secret of Harmony").

Overview
Due to their own emotional hang ups, Musa and Riven have had difficulty understanding one another. Having first met in the Black Mud Swamp in the episode of the same name, Musa quickly developed a crush on him, initially drawn to the air of mystery she believed he held behind his tough exterior. Unfortunately, Musa's feelings were left unrequited as Riven seemed to want nothing to do with her and seemingly enjoyed teasing her. To make matters worse for Musa, Riven began dating Darcy, which Musa finds out about when she unintentionally catches them having a private moment in the episode "Betrayed!" As Riven continued dating and working for Darcy, Musa slowly set aside her feelings after seeing him less as the bad boy she was initially drawn to and more as a terrible, overly hostile person.

Despite it all, Musa and Riven are seen as friends in Season 2, after Riven had properly redeemed himself, and later become a couple by the season finale after Musa kisses him while under the impression that she had lost him to Lord Darkar's attack. All seemed well until Season 3, where their relationship hit such a rough patch that Musa frequently contemplated a possible breakup. This instance eventually led to a string of on-and-off romance between the two as, whenever they faced a potential breakup, the two were suddenly drawn closer than before and would rekindle their romance only for the cycle to repeat itself about a year later.

Instances of this would come in the form of Riven fighting for Musa with Ophir under the assumption that he was trying to steal her away, Riven's bout of jealousy at Musa's budding career in Season 4 due to her new manager, Jason Queen, Musa's suspicions of Riven cheating on her in Season 5, and Riven's suddenly cold demeanor in Season 6, which seemed to have broken the pair up for good.

The constant on-and-off nature of their romance often left Musa feel like she was walking on eggshells, as reflected in her song, Heart of Stone, where she describes how she frequently felt like she could never fully understand Riven due to him bringing her emotions up and down so much to the point where she felt like she was losing her mind. Despite Musa's best efforts to reach out or even change Riven, he would always default back to being cold and emotionally withdrawn, further drawing a rift between the two. As for Riven, despite his own efforts to make their relationship work and keep Musa happy, the very fact that their relationship was so rocky proved that the two of them could not fully salvage it, resulting in their final breakup in "The Anthem."

Songs
As a couple, Musa and Riven have songs sang by either one or both of them:

Quotes
"Do me a favor. I just want to hear you say... that you'll come back. You'll come back... to me."

"Being with you makes me feel at peace in harmony."

Trivia

 * Musa and Riven are the only main couple out of the others to have gone through a major breakup. Twice, in fact.
 * They are also the only main couple to break up willingly, as Aisha and Nabu were forced apart due to Nabu's death.
 * Ironically, Musa and Riven do not go through the most break ups in the comics as they only go through two (almost three) notable ones. That claim goes to Stella and Brandon with four.
 * Supposedly, Musa and Riven's relationship was meant to end with their breakup in Season 4 but Rainbow backpedaled on the decision upon noticing the negative fan reaction, which resulted in the two giving their relationship another chance by the season finale.
 * Much like Bloom and Sky, Stella and Brandon and, later, Aisha and Nex, at least one party in the relationship has an ex-lover. In this case, Riven dated Darcy for most of Season 1.
 * While counting down to the eighth season's premiere, the Winx Club Instagram released teasers of #15reasonstowatchwinx8 on their account throughout March and April, 2019. Reason number 1 was Riven's return, which was a kind of spoiler to restore Musa and Riven's feelings this season.
