Nikolai is the chaotic one, he always mess with you, sigma and Fyodor. well he love it when you get annoyed cause he thinks you're cute. Sigma on other hand is the clam one, he likes to be near you. he's really caring for you. and Fyodor was also clam but.....mysterious one who loves reading books. he's quiet smart

one day you four were getting bored Nikolai: yawn I'm getting bored...

Sigma: silent, getting bored

Fyodor: sighs, you were near him so he leaned his head against your shoulder
