With which concept should debut ZB1?

First of all I thought from the first time I heard it that they were going to use the logo song as the intro or part of their debut song, and so it would be associated with space just like Kep1er's debut song.

(The first 10 seconds) (I put this because the M Countdown videos have the longest version of it)

Aside from that prediction. I predict they will have a concept just like X1's debut, just like exactly what people expect, because I feel like if they did anything too different or weak it would be disappointing people's expectations. Again just like the Produce theme songs and Wa Da Da, it will be streamlined, corporate, and bizarre.

If they can deliver a bop like Flash or Energetic than I will be seated. I don't really care about the concept but they will probably go dark? I don't trust boys/girls planet because they gave kep1er 'wa da da' as their debut and that song was a bit sick to me so I need them to slay

Bright and elegant suits them the best

Don't think dark will do anything for them
