Ya'll are in for a ride if you stick through this. It is now on episode 5, episode 3 and 4 are an hour long. You all will be fans of Simon by the end of episode 3 trust. This series is as raw as it comes when covering the beginning of an idol group. There is a heavy focus on the girls that don't make XG because they contributed to the creation of XG as much as the ones that made it.
Also note that just because girls didn't make XG doesn't mean they aren't with XGALX still. XGALX plans to continue creating groups and rumors have it they are putting together a boy group.
Hikaru wasn't cut from XG, she went to participate in GP99 under XGALX and ended up winning so she joined the group they formed.
Looking forward to the next ones!
