Niki is your bestfriend his a trouble maker and childish.

One day a the new student was being close to you and hanging out with you more often.

Niki noticed that you are hanging out with the new student more often than him as he spotted you alone in the library so he approached you and sat next to you as he spoke "Why are you and Kyle hanging out so much what about me.." He said with a pouty look in his face.
