Davichi continued their strong sales streak for the new single "Missing You Today," this week.

The duo's new song remains the number one song on the Billboard K-Pop Hot 100 in its second week on the chart, gaining critical approval along the way for members Lee Haeri and Kim Minkyung.

"Davichi remains strong and at the top of their game," writes Billboard reporters Jeff Benjamin and Jessica Oak.

And leaping seven places into number two on the Billboard K-pop chart is the girl group 2NE1 with their reggaeton-tinged hit "Falling In Love," also in its second week on the charts.

"Falling In Love" secured the number one spot on the South Korean pop chart Gaon last week.

The song is the quartet's 10th hit, according to the website Popdust.

And the only song to debut in the Billboard K-pop top five this week, Ailee's horn-infused "U&I" is at number three in its first week on the chart.

The singer injured her left ankle last week, leaving many fans to wonder if she would be able to appear in a scheduled performance on the Korean Broadcasting System program "Music Bank" to celebrate the release date of her new album "A's Doll House."

But a representative from the singer's record label YMC Entertainment told the South Korean publication Sports Chosun that Ailee was determined to perform.

"Ailee fell on July 10 and seriously injured her left ankle. She received treatment, but she is still experiencing pain. Yet, she showed a strong will to make her comeback, and she went on stage thinking of her fans who waited for her new album," the rep said.

"She will continue to receive treatment while continuing her album promotions."

After more than a yearlong hiatus girl group A Pink is back with a new song called "NoNoNo" and a new high-budget, brightly colored music video to match.

The video for "NoNoNo" features the girls palling around in home settings and offering up tightly rehearsed choreography in a giant white room.

Down from the number two position on the Billboard K-Pop Hot 100, "My Love" by Lee Seung Chul rounds out the top five with his dong "My Love."

It is the song's fifth week on the chart.
