With May just around the corner, girl groups will now be taking over the K-pop scene with full force. 4minute and SISTAR have already made their comebacks with a drastic change in concepts. Along with new concepts, they've returned with hot new tracks that have been topping the charts.

However, it's now time for the second batch of girl groups to make their comebacks. Sunny Hill, Girl's Day, A-Pink, and more are lined up as they gear up for a comeback in time for Spring.

Girl's Day is scheduled to release their 2nd mini album 'Everyday II' on April 18th. Their jacket photo shows the members in vivid outfits from hot pants to mini skirts, giving off a mature feel as they gradually grow out from their cute concept. The girls maintained a cute, lively image for their previous hits, "Twinkle Twinkle" and "Hug Me Once", but will now be going one step further into a combination of cute and sexy.

After successfully completing their promotions for "The Grasshopper Song", Sunny Hill will also be making a comeback this month. The four ladies will be on their own this time without the inclusion of their sole male member, Jang Hyun, who enlisted in the military back on January 31st. Sunny Hill is planning on making a grand comeback with a more profound, high quality performance on stage. Fans are highly anticipating the group's return and are looking forward to what kind of concept they have in store for us this time after their hit tracks, "Midnight Circus" and "The Grasshopper Song".

The news of A-Pink's comeback for the end of this month has alarmed and captured the attention of male fans. A-Pink, known for being different from other girl groups with their unique image, delivered a strong debut with "I Don't Know" and was able to steal the hearts of many. However, many are now anticipating whether their upcoming track will be able to successfully maintain their popularity.
