Rather than relying on heavy vocal processing or overpowering delivery, I.N uses subtle phrasing and controlled pitch shifts to express the speaker’s hidden sincerity.
This three-dimensional performance elevates the track from a standard background score to an essential narrative element for the drama.
The digital release includes both the main vocal track and its full instrumental version, allowing listeners to appreciate both the intricate instrumental arrangement and I.N’s vocal line in isolation.
Drama Context: Elevating the Narrative of ‘Love in Disguise’
To fully appreciate the impact of “Guilty Pleasure,” one must look at its placement within tvN’s romantic thriller Love in Disguise. Directed by Park Dan-hee and written by Moon Soo-jung, the series stars high-profile actors Yim Si-wan and Seol In-ah in a tense, fast-paced storyline.
The plot follows an arrogant third-generation chaebol heir who finds himself unexpectedly named a primary suspect in a murder investigation. To untangle the truth, a seasoned detective from a special forces unit goes undercover, disguising herself as his personal assistant and secretary. As the two navigate high-stakes danger, corporate intrigue, and mutual suspicion, an unexpected romantic tension begins to form.
“Guilty Pleasure” serves as the key musical backdrop during moments when the lead characters grapple with their dual lives. The track’s blend of upbeat urgency and emotional hesitation accentuates the drama’s blend of romantic comedy and suspense. By contributing to Part 4 of the soundtrack, I.N joins a curated roster of featured artists who help define the sonic identity of the broadcast.
Vocal Evolution: From ‘VOCALRACHA’ Maknae to Solo Soundtrack Vocalist
Since debuting with Stray Kids in 2018, I.N has continually pushed his boundaries as a performer.
As the youngest member and a core part of the group’s vocal line (often referenced alongside Seungmin as VOCALRACHA), I.N originally entered the music industry with a fondness for traditional trot music before refining his technique across hip-hop, EDM, and alternative rock genres.
Over the years, I.N has steadily built a portfolio of individual work that laid the groundwork for this solo OST debut:
- SKZ-RECORD Releases: Through Stray Kids’ informal release platform, I.N has shared original solo pieces such as “Hug Me,” “Maknae On Top,” and “HALLUCINATION,” showcasing his ability to write, compose, and execute self-reflective music.
- Unit Collaborations: He has demonstrated stylistic flexibility in unit tracks across Stray Kids’ studio albums, including “Gone Away” (with Han and Seungmin), “Can’t Stop” (with Seungmin), “Burnin’ Tires” (with Changbin), and “CINEMA” (with Lee Know and Seungmin).
- Live Performance Covers: His vocal versatility has been displayed through covers of acoustic ballads and rock classics on broadcast television and live streaming sessions.
Taking on a formal TV soundtrack as a sole featured vocalist represents a major step forward. Unlike group tracks where line distribution is divided among eight members, a solo OST requires the singer to hold narrative momentum across an entire song independently. I.N’s execution of “Guilty Pleasure” proves his readiness to take on larger individual projects within the Korean entertainment industry.
Broader Context: Stray Kids’ Global Activities and Momentum
The release of “Guilty Pleasure” arrives during an extremely active period for Stray Kids as a whole. Rather than slowing down group commitments, individual ventures like I.N’s OST are integrated into a broader schedule of international performances and physical album releases.
The “Run It” World Tour & Dome Shows
Currently, Stray Kids are in the midst of their massive “Run It” world tour. Following successful stadium dates across Asia, North America, and Europe, the octet is scheduled for a high-profile three-night residency at the Tokyo Dome. Selling out premier stadium and dome venues solidifies Stray Kids’ position as one of the top touring K-pop acts globally.
Japanese Release: ‘Suiatsu’
In addition to live touring, Stray Kids are preparing for the release of their fourth Japanese EP, titled Suiatsu, scheduled to drop on November 25, 2026. This marks the group’s first official Japanese project in nearly a year and a half, following the major commercial success of their previous EP Hollow, which sold over 610,000 copies on its release day and topped the Oricon charts.

Reception and Impact on Fandom Culture
Following the official 6:00 PM KST release on November 2, “Guilty Pleasure” quickly gained traction across digital streaming platforms and global social media channels. Stray Kids’ fanbase (STAY) celebrated the release across X (formerly Twitter) and online forums, using targeted hashtags to trend the announcement and stream the track on Spotify, Apple Music, and Korean streaming sites like Melon and Genie.
OST releases represent a unique promotional channel in the K-pop industry. While traditional group comebacks rely primarily on music video views and music show voting, TV soundtracks expose artists to general television viewers, drama enthusiasts, and international streaming audiences who might not otherwise follow idol groups.
For I.N, “Guilty Pleasure” serves as a dual-purpose milestone: it gives long-time fans a dedicated solo track to celebrate while introducing his vocal talent to new audiences watching Love in Disguise around the world.
Conclusion
With “Guilty Pleasure,” I.N has successfully crossed a milestone in his artistic career. By stepping up as a solo OST vocalist for tvN’s Love in Disguise, he showcases a mature pop-rock delivery that complements the series while establishing his standalone potential as a singer.
As Stray Kids continues to dominate global charts and tour stages, individual projects like “Guilty Pleasure” demonstrate the deep talent and versatility present within the group’s lineup.
