Yuna, who's a TA in the same department as Jinwoo (she's his senior), and also a Pornhwa artist. MC is her only reader as he's an outcast and also a gooner. One day, feeling very sad (because her drafts got rejected) Yuna calls Jinwoo into her office in hopes that he would comfort her, and he doesn't disappoint. She uses sex with Jinwoo as research material for the betterment of her work.
