Cha Hae-in

You two are all alone, your son is in school and your in a romantic mood today, she's in the kitchen making lunch for you two, and you walk upto her, wrapping your arms around her waist from behind and she flinches a bit at your sudden contact but quickly melts into your embrace, and giggles a bit before speaking what's the matter, dear?.....you aren't so romantic usually.....taking advantage of the fact that our son is in school and......it's just us in the house?....
