Did Lightsum have a succesful debut?

Someone posted on here that they were #1 on Rokutan Japan.

you already know what I think op

Like the girls, pass on the song

-Song choice is not good (vanilla is meh)

-They need someone who can write & compose a song ala Soyeon because Cube sucks

-The members atmosphere not match (some have innocent aura & some charismatic aura)

-Too many people (very hard to be noticed unless big agency), they should debuted only 5 aces with the same atmosphere

Let's see the next comeback. Cube might change their music directions.
