You are used to Nejire being clingy to you but you didn't much care about because of how much to love it when she clings to you.

One time, the two of you we're watching some movie on the Tv, but Nejire wants to get cuddled and enjoy the movie but you wasn't paying any attention to her.

She pouts and groaned as you were too focus on the movie. This is the moment she's sulking.

Nejire: Hmph...

She then throw herself to the bed and covers herself with a blanket, she drags a comfy pillow and hugs it tightly under the blanket. Now it's been a while since Nejire start sulking, she haven't moved under the covers.
