From trot to his own songs
I.N (아이엔) is a member of Stray Kids, the eight-member group under JYP Entertainment. On 18 July 2020, on MBC’s 최애 엔터테인먼트 (Choeae Enteoteinmeonteu), a show whose name reads as favourite entertainment, he sang Lee Mi-ja’s trot song ‘동백 아가씨’ (Dongbaek Agassi), a title that means the camellia lady (MK Sports).
The digital album SKZ-REPLAY, released on 21 December 2022, carries his solo song ‘안아줄게요’ (Anajulgeyo), a title that means I’ll hold you. Among the new solo songs whose lyrics and music the members helped write, SPOTV News introduced it as a song of fresh, fluttering feelings. He learned how to write songs within the team. In an interview with Harper’s Bazaar Korea in September 2026 he said, “I learned a lot about a feel for composing from Changbin hyung, and it was also what got me to understand a lot about my own musical colour,” and added, “Singing while playing the piano was my dream, you see.”
‘HALLUCINATION’ and ‘GENIE’
Soompi reported on 16 December 2024 that the music video for his solo song ‘HALLUCINATION’, on the special album 合 (HOP), had been released as the first instalment of the group’s self-produced series SKZ-PLAYER. ‘GENIE’ is a song from the Netflix series Genie, Make a Wish, and I.N’s voice went into it alongside Han’s and Felix’s, as Sports Kyunghyang reported on 28 October 2025.
Ambassador roles, and a birthday donation
Fashion and jewellery brands have made him an ambassador one after another. Soompi reported on 23 January 2025 that the Italian house Bottega Veneta had chosen I.N as its new brand ambassador, and on 8 May 2025 that the jewellery brand Damiani had announced him as its new global brand ambassador.
On his birthday, 8 February 2026, he donated 100 million won to the National Cancer Center. The money goes to treatment costs for cancer patients in financial hardship and to psychological care for child and adolescent cancer patients. He said he had wanted to share the love he received from fans, and that he hoped the days of people enduring long treatment would become a little warmer (Xports News).
