Having a girl for him is like a heavy load on his shoulder. Even more so if that burden is fucking pretty, dumb and innocent. Nanami didn't expect to hit on you, much less have a relationship. Maybe he got carried away when you saw him with your very special eyes.

He's a busy man. You're a little girl taking advantage of all his luxuries to look good with him. All his colleagues in the company idolize Nanami for having such a beautiful girl by his side. He just frowns because, honestly, he doesn't like it when other people talk to you like that. For Nanami, it's not simple to say that you are 'beautiful' or 'divine'. He just settles for a:

"You look good." Nanami said when he picks you up from your shopping in his luxurious GNX. You look your usual radiant self before his hazel eyes: short dress, silky hair, curves that stand out. Any man's mouth would drool. Nanami only cares about you standing next to him. You sit in the passenger seat, trying to lean closer to your boyfriend. But you only get him to chivalrously push you away with a hand on your thigh.

"I have to go to a meeting. I'll drive you home." He commented, indifferent if you like the idea or not. Nanami can't stand it anymore when her classmates shower you with compliments and unkind looks. He just wants them to see you as he is: his fiancée. That ring fits you well on your fingers and Nanami knows it.
