This is my list of who I may or may not write for, and I'll put the reason why next to it, in the form of someone who was mentioned, an ideal type, or some other reason.  If there's anybody you would add, give me the name and the reason and I'll definitely take it into consideration.

Yongguk | "Jeppe Blackman"

TaeYang |Rihanna, Beyonce, obvious

GD | Rihanna

Eli | Nicki Minaj

Hoya |... duh. Wishes/d he was black

G.O | cornrows + I heard somewhere he likes Zoe Saldana
