Omg I have another one.
In MAMAMOO’s My Star, before her rap, Moonbyul says the line “22 December, let’s light up the night sky”. 22nd of December is Moonbyul’s birthday! I also believe the reason she is named Byul (star) is because she was born on a night where the stars shone very brightly. Though that might be something I made up coz I can’t remember where I heard it from
in loona's dance on my own, i adore absolutely every second of it, but the line "i don't wanna be somebody who lets somebody hold me if they hold me back" is especially amazing, i love it
