Sandara Park is adored for her angelic beauty, but signing up with YG Entertainment's 2NE1 involves singing, dancing and rapping hard in bad-ass music videos.

Luckily for Blackjacks, MBC's new drama "Happy Ending Once More" is putting together Jang Na Ra, Yoo In Na, Seo In Young, You Da In and 2NE1's Dara in one cutesy and colorful fictional girl group called Angels, reports Soompi.

The teaser for the series is a vibrant music video for the song "Always For You" in which the girls showcase their sweet voices and innocent smiles.

"Always For You" is very akin to videos released in the late '90s.

The drama stars Na Ra, In Na, In Young and Da In as former girl group members who are now in their 30s. They face life outside of the entertainment industry and struggle to find love. Dara cameos as their former colleague who stayed in showbiz and is now a top star, reports All Kpop.
