How It Went Viral: Why It Exploded Now
1. An Explosion of Pent-Up Demand
Even within NCT Dream, Jeno and Jaemin are the duo fans have long and passionately wanted to see debut as a unit. Both members possess exceptional dance skills and visuals, yet without an official unit, fan-made compilations ('JenoJaemin compils') racked up millions of views — proving the demand. The announcement of an official debut was itself a news event.
2. SM Entertainment's 2026 Strategy
Under the SM 3.0 framework in 2024–2025, SM reinforced its multi-unit strategy by launching several NCT sub-units (NCT DOJAEJUNG, NCT WISH, etc.). JNJM represents the pinnacle of that trajectory — a strategic move to seize the K-POP market in the first quarter of 2026 by leading with Jeno and Jaemin, who boast the deepest global fanbases among NCT Dream members.
3. The SNS Virality of a 'Dichotomy' Concept
The title 'BOTH SIDES' itself gave fans endless material for interpretation, fan art, and meme creation. A teaser video released just before launch ("Which one is your best side?") ignited a 'Jeno side vs. Jaemin side' debate that spread virally through social media algorithms.
Context and Background
NCT Dream and Jeno & Jaemin's Journey
- NCT Dream formed: August 2016. Jeno and Jaemin have been founding members leading the team for nearly a decade.
- Both members have publicly expressed their desire to do unit activities in official interviews since 2023.
- Due to the nature of the NCT system, sub-units require SM's approval and the right timing — making this debut a milestone that fulfilled over three years of fan requests.
The K-POP Sub-Unit Strategy Trend
Sub-units have become a core growth strategy in the K-POP industry in 2024–2025. Unit comebacks are now more frequent than full-group comebacks, serving as an effective mechanism to lower fan fatigue and open the wallets of individual member fandoms.
Outlook: How Long Will It Last?
Estimated lifespan: 1–3 days (fandom peak) → Long-term (sustained unit activities)
- Twitter trending peaks within 72 hours of release. However, given that NCT JNJM has now established itself as an official unit, it is highly likely to become a long-term talking point through music show promotions, fan meetings, and photo shoots.
- Streaming chart performance on Spotify, Melon, and Genie will be confirmed within 2–3 days, generating a second wave of attention.
- Strong responses from international fandoms (especially in Southeast Asia, the Americas, and Europe) suggest global media coverage will follow.
Checklist
Secondary Issues and Risks
- Risk (Low): Fan response is overwhelmingly positive at present. However, some fatigue over SM Entertainment's multi-unit strategy ("too many units") has been noted by some.
- Misinformation risk (Low): As an official SM release, the risk of false information is low.
- Derivative issues: A 'who's more popular?' debate between Jeno and Jaemin's individual fanbases could escalate into internal fandom conflict, though this remains within the normal range of K-POP fandom culture.
