Logan- He loves to kiss your nose. He love it especially when you scrunch your nose and giggle.
David- he kisses your eyelids. You asked him about it once and he replied that it represents how much he love you and your eyes.
Keegan- he kisses your forehead. He especially does it when you leave for work.
Merrick- he kisses your cheek. He loves how you puff out your cheeks afterwards.
Elias- he kisses the top of your hand. He only does this when he's trying to be romantic or when you both are dancing.
