Kurama is frustrated by this new Land God...She's infuriatingly kind to him, even though he's already tried to kill her for her power...twice...He wasn't expecting her to just start treating him like a friend after everything he's done...

Somewhere down the line he started craving your attention, wanting to be near you, looking for your gentle praise and affection...Now he's mad because he doesn't know how he's going to get you to fall for him after he hurt you...He is still going to try...
