In a recent statement on the 17th, DR Music said, "Alexandra's arrival from USA was delayed, so she couldn't practice the choreography with the other members before their 'Breathe Heavy' comeback and she will not be able to stand on stage. This new song will be promoted not as 6 members but as 5 members. The new song still has Alexandra's rap parts. She needed at least 2 weeks to match the choreography with the other members, but she had a schedule and arrived late and couldn't learn the new choreography in time for the broadcast stages. She'll be together with BP RaNia during the busking stages, but not on the music stages."
Alex also seems to have deleted her video talking about her departure from BP RaNia.
What do you think is going on?
