SOOSOJIN RAIN MV Puts Trio in Focus

SOOSOJIN's new official music video RAIN puts a still-emerging three-member Korean group back in front of listeners with a release that is easy to identify in both English and Korean. The clip is titled [MV] SOOSOJIN(수소진) _ RAIN(슬픈 비가 또 내리고) on YouTube, pairing the group's romanized name with 수소진 and giving the song a Korean subtitle that translates literally around the image of sad rain falling again.

The video was uploaded on September 23, 2026, through 1theK, the K-pop media channel operated as a discovery hub for Korean music videos and artist content. Official metadata lists the video ID as xvJyYMgyDQQ, with an embed at https://www.youtube.com/embed/xvJyYMgyDQQ, and a runtime of 177 seconds. The source description marks the upload with #NEWRELEASE and #MV, making the release status clear without relying on outside speculation.

For readers meeting the name for the first time, SOOSOJIN is not a solo alias or a one-off project credit. Melon lists SOOSOJIN as a Korean female group with three members: Su, So and Jin. The same profile identifies Brotherhood Entertainment as the group's agency and places the act across ballad, dance and rap/hip-hop, a combination that gives the group more than one lane as it builds its public identity.

A Release Built Around Name Recognition

The most important function of RAIN at this stage may be clarity. Newer K-pop groups often have to teach audiences several identifiers at once: how to spell the romanized name, how the Korean name appears, who the members are, which company is behind the act and what previous release should be used as a reference point. This upload brings several of those pieces together in one official listing.

That matters because SOOSOJIN's searchable footprint is still young. Melon lists the group's debut date as December 18, 2025, with 아직 너를 사랑하는 건 맞아(Prod.로코베리). A September 2026 music video therefore lands during the period when each release can still shape the first public impression of the act. Rather than functioning as just another clip in a long catalog, RAIN becomes part of the basic map of who SOOSOJIN are.

The song title also helps the release travel. RAIN is short, direct and easy for international listeners to remember, while 슬픈 비가 또 내리고 gives Korean-language searchers a more specific phrase. In practical terms, the double-title format helps connect audiences who may search in different languages but are looking for the same official video. That kind of title architecture is small, but for a developing group it can make discovery cleaner.

The Trio Profile Behind the MV

SOOSOJIN's group structure is central to the article because it is one of the few fully verified artist facts available from a music-platform profile. Melon identifies the members as Su, So and Jin, a naming pattern that also explains the group name itself. The profile does not provide detailed member biographies in the available text, so the safest reading is focused on the group unit rather than individual backstories.

The genre spread listed by Melon is also useful. Ballad points toward emotional vocal material, dance suggests performance-led presentation, and rap/hip-hop opens room for rhythmic or spoken delivery. Those labels should not be treated as a detailed description of RAIN without additional production notes, but they do explain why a music video is an important format for the group. A visual release can show how the members occupy a song across mood, movement and image even when only limited official information is available.

Brotherhood Entertainment's listing as the agency gives the release another anchor. Many English-language K-pop readers follow companies as closely as artists, especially when a group is still gaining name recognition. Including the agency connection helps place SOOSOJIN in an industry context while avoiding inflated claims about popularity, chart position or promotional scale that have not been verified for this specific video.

What 1theK Adds to the Official Trail

1theK's role in the release is not simply that of a video host. The channel description attached to the YouTube source states that 1theK is an official channel for music video distribution and that views from 1theK uploads count toward music show rankings. That statement is a factual part of the upload context, though it should not be mistaken for evidence of any particular ranking result for SOOSOJIN.

The broader 1theK site describes the brand as a global K-pop media platform connecting artists and fans worldwide. It also says 1theK reaches more than 35 million subscribers across YouTube, X, Instagram, Facebook and other platforms. For a group at SOOSOJIN's stage, that kind of established channel identity gives an official release a recognizable setting for casual discovery, especially among viewers who browse new K-pop videos through 1theK rather than through individual agency accounts.

The official 1theK description also keeps the release framed inside K-pop's normal viewing infrastructure. The video is not presented as a fancam, a repost or a fan-made edit. It is an official MV upload from a music channel that explicitly describes itself as part of the distribution pathway. That distinction matters for editorial coverage because it separates article-worthy source material from unofficial clips that may circulate around the same artist name.

No Chart Claims, Just a Clear Next Step

Because the verified source material does not include chart positions, streaming totals, music-show nominations, concept photos, lyrics or agency statements about the production, the responsible frame for RAIN is a release report rather than a performance report. The news is that SOOSOJIN have an official MV out through 1theK, backed by a platform profile that identifies the group, members, debut date, agency and genre range.

That may sound modest, but modest facts can be valuable when an artist is new. For fans who have just encountered the video, the immediate questions are basic: who is SOOSOJIN, how many members are there, when did they debut, and where can the official MV be watched? RAIN answers the last question directly, while Melon's profile fills in the first layer of group context.

The next useful signals will come from additional official materials: live clips, music-show stages, platform credits, performance videos or agency notes that explain the song's concept in more detail. Until those arrive, RAIN stands as a concise official entry in SOOSOJIN's early catalog, one that strengthens the connection between the group's English name, Korean name and member-based identity.

For now, the release gives SOOSOJIN something every young act needs: a verified visual marker that can be embedded, searched, shared and connected back to a clear artist profile. In a crowded K-pop environment, that clarity is not a small thing. It is the foundation on which the next round of recognition is built.
