WAIT NO FUCK MY PREVIOUS THEORY

Shin Yooyoung has two souls coexisting in his body. The two young masters that appeared in his dream. I feel like the white haired one has more control over his body because of the amount of hair that became white, the roots are still black so I think the toxic husband has little control of the body but maybe takes control during some sex (?) or when his angry. Anyway those two are definitely related, brothers or something because they’d have to have some sort of connection if they share the same conscience. Maybe before the crash the husband was only in control since his hair was all black and he managed to sway Kwon to come woth him overseas. After he awoke from being hit by the car (was it a car or truck I kinda forgot) the white haired bro was awakened and that’s why he was so persistent to see Kwon for himself.
TAKE THIS WITH A GRAIN OF SALT BECAUSE WHEN WE GET MORE LORE I’LL MAKE ANOTHER THEORY UNLESS IT MERGES WITH THIS ONE (?????)
