JUNNY will release the OST Part 4 of the TVING original series "Yumi's Cells Season 3," titled "Into My Life," on the 28th at 6 PM through various music streaming platforms.

"Into My Life" is a medium-tempo pop track that starts with an acoustic guitar and gradually intensifies with synthesizers and drums, following the emotional line. It captures the feeling of emotions returning like fate at a moment when one did not want to believe in love. JUNNY's delicate vocal tone is expected to maximize the excitement of the song.

Last year, JUNNY successfully held a world tour with his second full album "null" and has been actively releasing various music content, continuing his activities into 2026. This participation in the "Yumi's Cells Season 3" OST marks his first OST activity in 2026.

"Yumi's Cells Season 3" (directed by Lee Sang-yeob, written by Song Jae-jung and Kim Kyung-ran, provided by TVING, produced by Studio Dragon, Merrycow, and Studio N) stars actors Kim Go-eun and Kim Jae-won. The series is exclusively pre-released twice every Monday at 6 PM on TVING and airs once every Monday and Tuesday at 8:50 PM on tvN.

"Into My Life" will also be inserted throughout the series.
