"Nicole couldn't understand by looking at his behaviour that what he is thinking now? There was neither any angry type expression not any mischievous type expression. She started to feel guilty that why even in the first place she was dressed up for him. It's so embarrassing for her that she asked him how does she looks and here he just ignored her like nothing has mattered to him.
On the other side he was just couldn't believe that she really is dressed up for him. It is just too much for him to handle. He couldn't describe that how wonderful she is looking right now. Actually he thought that there is no words exists in this world to describe Nicole's beauty. So he thought that once they reached the house then he will made her believe that how much of gorgeous is she looking right now through his actions.
