Kim Seok-jin

On June 4, 2019, Kim released his first independent song "Tonight" as part of the 2019 BTS Festa, a yearly event celebrating the anniversary of the band's debut. The acoustic ballad was composed by Kim, alongside Big Hit Entertainment record producers Slow Rabbit and Hiss Noise. The lyrics, written by Kim and BTS leader RM, are inspired by Kim's relationship with his pets. The track was met with a generally positive reception, with praise for Kim's vocals and the song's calming atmosphere.

Kim is a tenor and can play the guitar. Critically, his singing voice has received a generally positive reception. In Kim Young-dae's 2019 novel BTS: The Review, members of the Grammy panel stated that his voice has stable breath control and a strong falsetto, calling it a "silver voice". Journalist Choi Song-hye, writing for Aju News, wrote that BTS singles such as "Spring Day" and "Fake Love" displayed Kim's vocal stability, while the b-side "Jamais Vu" did so for his emotional range. Hong Hye-min of The Korea Times described Kim's voice as "tender, sorrowful, [and] free-spirited" and considered it to be the "standout element" on the solo ballad "Epiphany". Critic Park Hee-a, when discussing "Epiphany", stated that Kim "sings the most sentimental emotions" of the solo tracks on Love Yourself: Answer. In a review of "Fake Love", Park said that Kim's belting "prove[d] [the song's] effectiveness".

On August 9, 2018, the second solo by Kim, "Epiphany", was released as a trailer for BTS' then-upcoming compilation album Love Yourself: Answer. The song was described as a "building pop-rock melody" by Billboard and contains lyrics discussing self-acceptance and self-love. The full version of the song was eventually released as a track on Answer, peaking at number 30 on the Gaon Music Chart and four on the Billboard World Digital Singles Chart. In October, he was awarded the fifth-class Hwagwan Order of Cultural Merit by South Korean president Moon Jae-in along with other members of the group.

In 2018, he was ranked as the 11th most well-known idol in South Korea, via data collected by analytics company Gallup Korea.

In December 2018, Kim donated various supplies to the Korean Animal Welfare Association to celebrate his birthday, purchasing food, blankets, and dishes for the organization. He also donated 321 kilograms of food to the Korea Animal Rights Advocates (KARA), another Korean animal welfare non-profit.

Since May 2018, Kim has been a monthly donor to UNICEF Korea, requesting that his donations be kept private at the time. They were eventually publicized following his induction into the UNICEF Honors Club in May 2019 for donating over ₩100 million (about US$84,000).

As of 2018, Kim lives in Hannam-dong, Seoul, South Korea. Additionally, he and his older brother opened a Japanese-style restaurant in Seoul called Ossu Seiromushi in 2018.

While in junior high school, Kim was scouted by South Korean K-pop agency SM Entertainment off the street, but he rejected the offer at the time. He initially intended to be an actor, attending Konkuk University and graduating with a degree in art and acting on February 22, 2017. He enrolled in graduate school at Hanyang Cyber University, to pursue studies in areas other than music.

Kim collaborated with fellow BTS member V on the song "It's Definitely You", released as part of the Hwarang: The Poet Warrior Youth original soundtrack. He also joined BTS member Jungkook to sing and release an alternate version of "So Far Away", a song from BTS member Suga's self-titled mixtape Agust D. Kim's solo covers include "Mom" by Ra.D, "I Love You" by Mate, and "In Front Of The Post Office In Autumn", originally by Yoon Do-hyun in 1994. They were released on SoundCloud on May 7, 2015, December 3, 2015, and June 7, 2018, respectively. He has also made several appearances as a co-host for Korean music award shows, such as Music Bank and Inkigayo.

Kim was scouted by Big Hit Entertainment for his looks while walking down the street. At the time Kim was studying acting and had no background in music. Subsequently, he auditioned for Big Hit as an actor before becoming an idol trainee. On June 13, 2013, Kim made his debut as one of the four vocalists in BTS with their debut single album 2 Cool 4 Skool. Kim released his first co-produced track, a solo single from the album Wings titled "Awake", in 2016. The song peaked at number 31 on the Gaon Music Chart and six on the Billboard World Digital Singles Chart. In December 2016, he released a Christmas version of "Awake" on SoundCloud.
