lol, r u reading a romantic novel ? well, 莫少 is kind of a childe. if u put 少 after a family name, like this one, u call a young man who is usually the son of a rich old man. and this name is a way of showing respect. and 你亲够了没 is literally have u got enough kisses from me ? and this scene normally shows in a specific novel genre like what u just read.
