Hisoka:
Yeah he can be creepy sometimes, we all know that, but this man will absolutely NEVER overstep his bounds with you. He's a very affectionate guy but mostly in private and even then, he wants you to be comfortable. He's really big on cuddling too and he prefers to sleep spooning you, or holding you in some way. If either of you are away, he has a hard time sleeping without your company. It took him some time to actually admit that he had a hard time sleeping without you beside him because he wanted to be certain that you were safe.

Illumi:
He's really big on romantic gestures...in his own way. Illumi's never really been in a relationship before and isn't really sure how to show he cares, so he spoils you often with fancy things. After communicating that he doesn't need to spend a ton of money to make you happy, he starts doing things like leaving you short little notes when he leaves for a mission. He also often gives you roses for no reason and leaves them on your nightstand. Even though you had asked him not to, he still buys you expensive gifts every now and again.

Chrollo:
Chrollo has a major soft spot just for you and you're the only one that gets to see him like that. After being with Chrollo for a while, he let his guard down and you found out how sweet he really is. Not even the Phantom Troupe knows him as personally because he feels like he can be completely honest with you. Chrollo trusts you a lot and cares deeply about you and likes to show that whenever he can. He loves to keep you close by, wether that be holding you on his lap, holding your hand, playing with your hair, or holding each other as you both sleep.
