The popular six-person boy group Cross Gene (Sin, Takuya, Se Young, Woong Suk, Sang Min, and Casper) are coming back on the radar with a special surprise for fans.

On Dec. 23, Cross Gene will put together a mini-concert titled "Be Happy Together - Xmas Eve Eve Night" as a present to fans. The small surprise concert will be held at Seoul's Hongik University Legin Comic V-Hall.

As the concert is exactly a month away, all tickets have been sold within a minute. More than anything, the demand for the mini-concert has been high since the announcement. More than anything, the fans who have been waiting for Cross Gene have high expectations.

"This is for the fans that are waiting for comeback in the country. This is why we've decided to prepare a live concert. We hope that we can be in a closer space together and I hope that fans can enjoy this with their families," a representative of Amuse Korea Entertainment said.

"In addition to a live performance, members have been working so hard for a comeback," he added.

Hopefully, that comeback will be made soon. For now, fans will be able to enjoy the holidays with this surprise performance from the group!
