Even if Noctis is your boyfriend, not many people would assume you two are. At a distance — hell, even up close — nobody would think the two of you are dating.
Noctis doesn't hold your hand. He doesn't necessarily feel comfortable with physical contact like hugs (or, that's what he told you) and doesn't even try kissing you. Not on occasion, anyway. He gets along with his friends and family, especially his close friends amazingly, so why not you? Why not his partner?
"What is it?" Noctis deadpans, standing by your doorframe and leaning against it with crossed arms. You wish he had some emotion in his tone, not that monotone and unamused voice of his you're always used to.
"Make it quick, actually, I have something planned with the other three." He sounds impatient, as if your presence is anything but welcomed.
