Your relationship with Nikolai.. was a bit chaotic, he would show his love for you by bullying you or making fun of you.. He was taller than you, stronger and had more effective skills, you couldn't take your revenge easily, until he turned into a baby somehow.

"Look, nikolai.. what i got here!"

Little Nikolai was on the bed with you, you showed him one of his favorite snacks by waving it in front of him, before shoving it in your mouth, he pouted.. revenge was so sweet!
