5th-gen boy group ZEROBASEONE (ZB1) made a successful debut with their first mini album "Youth In The Shade" on July 10. Since then, the boys have been actively promoting their album on music shows and variety programs, as well as media interviews and magazine shootings. 

Right after the album promotion, ZB1 immediately held their first ever fan-con in Gocheok Sky Dome on  August 15. In order to allow ZEROSE around the world to enjoy the show together, the fan-con was live-streamed online with English, Chinese and Japanese subtitles. Various CGV cinemas across Korea also provided live streaming of the concert. 

The concert started at 7:30pm sharp. The members appeared in white suits on a lift stage decorated with white roses, while singing the first song in their album "Back to ZEROBASE". Then, the boys performed an upbeat, retro style b-side track "New Kidz on the Block", followed by "Say My Name", one of the most popular mission songs from "Boys Planet", the Mnet audition program that formed the group.

After performing three songs in a row, the boys had a chat with the MC actress Park Seul-gi. The members shared their excitement for holding their first fan concert, saying that they were very grateful to receive so much love and support from their fans. Leader Sung Hanbin even confessed that this is the happiest moment since his debut. 

Next, the members changed to black outfits and performed a sweet b-side track "and I", followed by the "mission section", which was the highlight of the fan-con. Each member took turns to complete different missions to demonstrate their diverse charms. For example, Kim Jiwoong took 4-cut shots to show off his perfect visual, main vocal Kim Taerae sang songs according to different situations with his sweet voice, and the youngest member Han Yujin performed lovely aegyo which melted the hearts of all ZEROSE and the other members.

After playing games, ZEROBASEONE performed a few more songs, including "Boys Planet"'s theme song "Here I Am", the two final mission songs in the audition program "Jelly Pop" and "Hot Summer", and the title track of their album "In Bloom". The members even added a dance break section in "Jelly Pop", during which each of them show off their dancing skills one by one. Finally, the members performed "Our Season" during encore, bringing the fan-con to a perfect end. 

After the fan-con, each audience of the cinema live streaming were given a set of semi-transparent special photocards with all the members. Of course there is no comparison between watching the fan-con at the venue and through a screen. However, enjoying the show in the cinema with other fans was still an interesting experience overall.
