jang hayoung in her original universe, had a female body and identified as a girl . But the character she possesses in the orv universe is biologically a male . So basically she's a transmigrater from an another dimension

When she couldn’t recall the past properly, she’d even start pinching the sleeping Kim Dokja’s cheeks. And when her resentment flared up for no reason whatsoever, she’d even write some weird things in the novel, as well.

The dokkabai king from the 1863 turn

kid dokja is od

. And when then she couldn't write the final conclusion. With her last ounce of strength she ran on the street , where there is the subway dokja rides .
