Dara, Jang Na Ra, Yoo In Na, Seo In Young and You Da In transform into a girl group for 'Happy Ending Once More'

This has got to be one of the best ways to tease a drama ever. Upcoming drama 'Happy Ending Once More' is about the former members of a once popular girl group, now all grown up in their 30s.

And the drama has released an MV for the song "Always For You" by the fictional girl group Angels, whose members (and stars of the show) are Jang Na Ra, Yoo In Na, Seo In Young, You Da In, and 2NE1's Dara in a special appearance!

The first four actresses play the main characters in the drama, who aren't in the entertainment business anymore, while Dara will make a special appearance in the drama as a top star.

The MV is completely reminiscent of the girl groups of the late 90s, down to the hairstyles, cute concept and very bright lighting.

It reminds us a little about the 2011 drama 'Greatest Love', which Yoo In Na also starred in!

'Happy Ending Once More' is currently airing on MBC.
