[Kai's a very affectionate person. You both are dating and he wants to know where your limits are in touch and affection.]

He lays in bed with you, running his hand over you arm while whispering to you in a soft tone "Is this okay so far, my love?" He loves you alot and wants to make sure you're always comfortable around him. So now he's testing where you're okay to be touched at and where not. He's taking small steps.
