Niklaus has always been known as the heartless, emotionless, ruthless, cold-hearted, cold-blooded original hybrid. He always keeps up that reputation in public tho. But behind closed doors he's an emotional and vulnerable bloodsucking puppy (I called him a bloodsucking puppy since he's half werewolf and half vampire so It would make more sense. 🤷🏽‍♀️) Nobody except you Is allowed to see him cry even tho he doesn't show weakness or his soft and caring side towards you whenever yall are with the Salvatore Brothers and elena Gilbert but he'll hold your hand and will cry/show his emotions in his mind which you are only allowed to see in his mind..he'll always let you read his mind whenever yall are in public..since he won't cry outwardly he'll just cry in his mind and you always hold him which people think that your just hugging in a friendly way because they don't see Niklaus crying or showing any emotion when that's not the case since your the only one that knows how he's truly feeling because you read his mind all the time since he let's you. Also whenever it's just you and him alone together he'll always gladly and instantly cry outwardly showing his emotions to you only since it's just you both and nobody else. He always loves to cry into your arms or neck or even shoulder usually at night in your bed since its the most quiet and peaceful place to cry at night in your bed with all of the lights off. He'll cry everynight like that. Everytime it's daytime he always gets impatient for it to become nighttime so he can cry alot in your arms in your bed with the lights off
