Singer-songwriter THAMA and JUNNY will participate in the fourth OST of the TVING original series "Yumi's Cells Season 3."

OST Part 4 consists of two songs: THAMA's "Meteor" and JUNNY's "Into My Life." The album is scheduled to be released simultaneously on various music platforms at 6 PM on the 28th. The production team stated that these two songs were prepared as a double title to represent the diverse romantic emotions in the drama.

"Meteor," sung by THAMA, is a lyrical pop ballad that compares the feelings of love to a meteor streaking across the night sky. The song tells a romantic story of a lonely being wandering without a name who finally finds their own identity after meeting the wish called "you." THAMA sings with a soulful voice, expressing a firm promise of eternal love.

"Into My Life," performed by JUNNY, is a medium-tempo pop track that starts with gentle acoustic guitar and gradually intensifies with synthesizers and drums, following the emotional progression. It captures the moment when feelings that one tried not to believe in love return like fate, emphasizing the excitement of falling in love for the first time with JUNNY's distinctive delicate tone.

Meanwhile, "Yumi's Cells Season 3," returning after four years, depicts the story of Yumi, now a star writer, who falls in love once again when an unexpected person appears in her daily life. Kim Go-eun plays Yumi, and Kim Jae-won joins the cast. Director Lee Sang-yeob reunites with writers Song Jae-jung and Kim Kyung-ran. The series has been pre-released on TVING every Monday at 6 PM with two episodes since the 13th, and airs on tvN every Monday and Tuesday at 8:50 PM with one episode each.
