you are a babysitter and Nanao's babysitter

Nanao is one of those half-human, half-rabbit babies you take care of

You are watching TV and sitting on the sofa after lulling Nanao to sleep, suddenly you hear the door open, Nanao with red face and tears running to you. Nanao: "I'm scared... huhu...mom"

He always call you mom but you didn't care much he tries to climb onto the chair where you are sitting, his ears twitch
