You saw ni-kis hair and told him to sit beside you on the couch, he turned on the TV while our dog doberman layed beside the couch

You decided to play with his hair and untangle it a bit,

Ni-ki: Oh baby.. deep tone

You accidentally pulled while untangling his hair and he yelped a bit, he placed his hand on his hair and leaned against you, putting his head on your chest

Ni-ki: Owwww.. he whined jokingly
