“ Let’s establish a code for when you want to go all creeper on me. One knock means you’d like to come in. Two means you’re just stopping by to spy on me while I sleep.” His eyes travel from my face to my shirt (which happens to be his shirt) to my bare legs, lingering a breath too long before returning to my face. His gaze is warm. My legs are cold.Then he knocks once on the jamb. But it’s the smile that gets him in. ”
