KARA will be making a return to the Japanese music scene with their 8th single!

Though more details have yet to be revealed, "Bye Bye Happy Days!" is reported to be the A-side track on the single, and the coupling track is called "My Boy". Ahead of its release on March 27th, all three versions of 'Bye Bye Happy Days' are currently taking up the top 3 spots on cdJapan's real-time chart for pre-orders.

It looks like they're going for a cute and lovely concept. What do you think?
