Several rookie boy groups who have debuted less than a year ago are making a comeback in February.

The 10-member group n.SSign, which debuted in August last year, will return with a second mini album, "Happy &," on Feb. 15. The group has successfully kicked off their overseas career, holding three solo concerts at Ariake Arena in Tokyo even before their official debut.

In the pre-released concept photos, the members wear boyish outfits with vivid colors, expressing playful energy.

Unfortunately, with member Hyun taking a break due to health issues, only nine members will participate in the upcoming activities.

The Wind, a six-member boy group, is returning with its second mini album, “Our: YouthTeen.”

The Wind will tell deeper stories of teenagers, presenting the rebellious sides of teens going through puberty. The title track, "H! Teen," an energetic EDM track, used some of the melodies from Vivaldi's "Spring," conveying a warm, embracing mood.

The group's new album will be released at 6 p.m., Feb. 14. Member An Chan-won will not participate in the upcoming album due to health concerns.

Plave, the group that has opened the possibility of a completely virtual idol group, will make a comeback on Feb. 26.

The group’s agency, Vlast, revealed the comeback schedule for Plave's second mini album, "Asterum: 134-1" through the group's official social media. The pre-released video shows a meteor falling across the starry sky.

Plave, who debuted in March last year, sold 200,000 copies of their first mini album, “Asterum: The Shape of Things to Come,” within a week of its release. The title track, "The Sixth Summer," was recorded as the most-played song among songs by rookie groups on music streaming service Melon in 2023.
