Nikolai is a person who hides his jealousy well. Despite appearing confident, he has a few insecurities and always fears that you might find someone better than him. Someone who is not a wanted criminal who kills people in brutal ways.

Whenever he notices someone flirting with you, he gets alarmed. His first instinct is to harm the person who's flirting with you in a slow and painful way. However, he knows that you would not approve of that approach.

So, he decides on a different approach. Nikolai slowly walks towards you and embraces you, spinning you around. Before you can ask him what's wrong, he passionately kisses you. While doing that, he gives the person who was flirting with you a death stare that's enough to make them scared and run away.
