I don't know how to explain it...
And this had nothing to do with the bullying accusations.
I think Garam got really good lines, prominent ones... Soojin also used to receive good lines without being main vocalist.
Both have a "witchy" voice that pulls you in. Garam has a softer and innocent witch voice while Soojin was more like a succubus, seductive and soft evil voice.
Both have a quiet feeling in real life while on camera they are more energetic (?)
There's something about their faces too...
Welp, I miss Soojin so much I guess .
