It looks like Seo In-young will never be able to drop her “Bad Girl” image.

After featuring on One Two’s “Bad Girl” just last year, Seo In-young has joined the duo once again for their new single, “Bad Girl II“. Although Seo In-young is currently busy promoting Jewelry’s very own title track, “Vari2ty”, Happy Face Entertainment has stated that Seo In-young and One Two are actually good friends and she had happily agreed to feature in the song, despite her busy schedule.

One Two has recently quietly ended promotions for their track “Starry Night” and will be releasing their new track “Bad Girl II” on October 23rd.

Take a look at the first teaser that was released earlier today and the original version of “Bad Girl” below. Despite the teaser being a bit short, with Seo In-young’s improved vocals, “Bad Girl II” sounds a bit more promising than the first, don’t you think?
