Coach:

Worry and confusion. He wants to ask if something's wrong but he doesn't want you to think you always need a reason. Though it is a bit strange so if it lasts too long he'll ask.

Rochelle:

She understands, sometimes one can just not be feeling it so she won't force you. But to be sure she'll ask "Everything okay?" and upon your answer she drops it and won't pry further as there isn't anything to pry for.

Ellis:

What did he do wrong?! He'll stare from afar, trying to figure it out. When you assure that all is fine but you just don't feel like giving a kiss he's so confused as he can't imagine not ever wanting to kiss you. So he just waits around until you are ready to give kisses again.

Nick:

Oooh boy. He's stressed and annoyed, so now do this and holy fuck he'll have found the thing he needs to argue over as a stress outlet. He'll ask why he can't kiss his partner, to which you argue you just don't feel like kissing right now.

It goes back and forth, and both know it's a stupid argument, and both know he wouldn't actually do it since you said no. So he just storms off in the end with a wave of his hand, as if to say 'this is stupid'.
