Sevenus (; presented in all caps) is a South Korean male duo formed by Heejae and Ireah, managed by PCS Entertainment.

Both Heejae and Ireah took part in the survival competition program Peak Time as members of their former ensemble Masc (; also stylized in all caps). After securing the runner-up position, they entered into an exclusive contract with PCS Entertainment on May 3, 2023, and re-emerged as a duo. The group revealed their new name, Sevenus, on May 9, 2023, which reflects their Team 7:00 identity from the show and emphasizes their bond with supporters through "us."

2016–2020: Masc's debut, endeavors, and disbandment

Masc initially debuted on August 19, 2016, as a quartet consisting of Heejae, Woosoo, 26, and ACE under JJ Holic Media. Their first mini album Strange was released simultaneously, featuring the title track of the same name.

Their follow-up single "Tina" was launched on February 4, 2017. Subsequently, Ireah joined Masc alongside Moonbong, Doeun, and Chibin with the release of their third single "Do It" on October 12.

In July 2018, following assault accusations involving ACE and Chibin, both members exited the group. Additionally, member 26 left to pursue a career in film. By October of that year, Masc resumed activities as a four-member lineup comprising Woosoo, Heejae, Ireah, and Moonbong.

The single "Maschera" was released on May 27, 2019. That year also saw Masc touring South America in May and Europe between June and July.

On October 18, 2020, Masc publicly declared their disbandment through a YouTube announcement.

2023–present: Participation in Peak Time as Team 7:00, reformation and release of Summús

In February 2023, Heejae and Ireah re-debuted as a duo on the JTBC reality competition Peak Time, performing under the moniker Team 7:00. During the show's finale in April, they disclosed their original affiliation with Masc and ultimately achieved second place. Following this success in May, they signed with PCS Entertainment and adopted the name Sevenus to concentrate on duo activities.

Sevenus unveiled their debut single album titled Summús on July 31, featuring "Wonder Land" as the lead track.
