Nikolai always be on your side. Showing up his tricks, trying to make you comfortable. He did all of that, it just him being.. Slightly too protective and possesive. You're talking to a guy that you said it was just a 'friend'.

"Don't you want to see another tricks? Perhaps, you want to be with him now?"

Nikolai whispered directly on ur ear as he grabs ur waist from behind, wrapping his arm around ur waist, his voice may be teased but having a extremely jealous tone inside of it.
