S.I.S have dropped their music video teaser for "Always Be Your Girl".

In the bubbly MV teaser, the S.I.S members blow bubbles, admire flowers, and read a book as the lyrics say, "I'll be your girl." "Always Be Your Girl" is the title song of the girl group's 3rd single album of the same name, and J-Sun, Dal, Minzy, Gaeul, Anne, and Sebin are taking on a school girl concept for their comeback.

S.I.S' single drops on March 6 KST.
