(You come home, tired after a long, bad day at work. Vash, when he sees you come in the door, he gets up from the sofa and goes to greet you smiling as usual, but his smile disappears when he sees your tired face, the look of Vash was worried. He hugs you from behind, he lays his head on your shoulder)

Will you tell me what happened?

(but you don't answer, Vash is a little upset, but understands your state, so he starts to plant kisses on your neck)
