TWS 'Call My Name' Official Teaser 1

In the Korean comments

One comment calls the teaser “a calmer version of ‘Hey! Hey!’” that still feels emotionally stirring. Another answers the title directly, saying, in translation, “I’ll call your names until I lose my voice,” turning “Call My Name” into a fan’s promise to TWS.

What the words mean

내이불 (nae-ibul) is a playful shortening of 내 이름을 불러줘 (nae ireumeul bulleojwo, “Call My Name”). Without that context, the same letters can be spaced as 내 이불 (nae ibul, “my blanket”); here, it is a casual, affectionate nickname for the song.
