Big Brain’s Debut Era


Big Brain released the hit single “Welcome” during their debut alongside a MV. The single is a kind of ballad love song filled with a piano instrumental and beautiful vocals from Big Brain’s members!

Big Brain’s Music Video

In the MV for “Welcome”, Big Brain’s members appear with a preppy style and hold vocal performances in several places. Other than that, there is a girl walking around the city with luggage in her hands.

Meanwhile, Big Brain’s members sing emotionally on a bridge, river, grave, and other places. The MV for “Welcome” is basically filled with bright colors and a minimalist concept that makes people focus on the music and vocals!

Big Brain’s Song Meaning


Big Brain came up with a ballad song as their first debut project. No wonder they considered themselves a ballad group, right? Regarding the song’s meaning, it is quite a complicated romance story due to unrequited love. “Welcome” narrates about a guy who has a crush on a girl, but she actually has someone else as her lover.

However, the relationship between the girl with her spouse isn’t really good which makes her go to the guy who secretly has a crush on her. Some of the lyrics also have a deep yet sad meaning such as “I was actually grateful to that person who made you cry,” and “There is a reflection of my love for you, for now.”

During their debut, Big Brain was busy promoting the single “Welcome” as well as performing on several music shows. One of their live performances took place on MBC’s Music Core! They appeared with a preppy-formal style that suited them perfectly.

Music Shows

Big Brain released another hit single titled “NO-YEs.” The group performed the song on Music Bank‘s live stage as well! They were dressed up in navy outfits with their iconic preppy-formal style. Meanwhile, Big Brain did not disappoint people with their vocal performance.
