It's always so sad to be able to see a group disband for whatever reason it may be, whether it be a contract expiration or things just don't work out, and the group ends up splitting. If you've been through a group breakup before, it's really heartbreaking, and there's always that glimmer of hope that just one day, the group can come together and be reunited once more. So here are five groups fans want to be reunited!

1. 2NE1: Without a doubt, 2ne1 has to top this list. With such a successful debut and chart-topping tunes, it's a mystery why 2ne1 disbanded. Even the members had to find out that they would no longer be together through personal acquaintances and the news media. As one of the most iconic groups, paving the way for many other fierce "girl crush" bands, 2NE1 is sorely missed by many! Their surprise performance at Coachella wasn't enough!

2. SISTAR: What is summer without the summer queens? After SISTAR announced their disbandment, many were disappointed. Who would give us the great summer tunes that'll be perfect for all the summer parties? I mean, who can forget the iconic moves of "Shake It," "Touch My Body," and "I Swear?"

3. MBLAQ: Another great group that unfortunately didn't last long. One of the most incredible things about MBLAQ was their diverse songs; they were always experimenting with different sounds, styles, concepts, and performances. Not one song sounded similar to another! Plus, on top of that, they were probably one of the funniest groups to appear on variety shows. You're surely missing out if you haven't seen them play the apartment game!

4. INFINITE: Although they're not technically disbanded, they haven't had group activities in so long. They're one of the first groups to really start from the bottom up. INFINITE achieved much success from their mega-hit "Be Mine," and there were so many other bops that came along, "Paradise," "The Chaser," and more! Plus, the fact that their logo always changed and the thrill of anticipating how the new logo would look was always such a great feeling. And, of course, you cannot forget the kings who made the "knife like" choreography so iconic.

5. U-KISS: U-KISS for sure didn't get the spotlight they deserved in the time that they were an actual group. This is unfortunate because their talents were overshadowed by more popular groups during that time. But they have some of the greatest classic K-Pop hits such as "Manmanhani," "Round and Round," "0330," and "Neverland!"

Honorable mention: Cross Gene, now not many people may know who they are, but Cross Gene is also a group with such great talent it went to waste due to poor management. They're funny; they have charm, vocals, and rapping. Truly, it'd be great to see them get back together!
