"In the garden of white magnolia I was born"
Something about that line gives me shivers (not necessarily in the dreadful way). It's very poetic and kind of evocative.
White flowers (and the color white in a general sense) symbolizes purity and innocence. So I could interpret this as starting off pure/innocent. Perhaps this is before something dark happens. Before being "tainted" so to say.
Magnolia specifically can mean purity and also represents love for nature, nobility, perseverance, and dignity. So it could be like starting off rich or growing in surroundings that give you the energy to be strong in the face of threat.
But my pretentious, art school brat might be coming out here. I just feel Wheein will tell an interesting story with this.
