"I shall take you out, so do not be too upset with me."
Now Andrew understood why she was strangely quiet since she saw him. It's because she overheard what the others have been gossiping about.
It still feels odd for him for saying it. However, he knows it will happen eventually. Andrew saw the markings on her calendar. When he saw that he couldn't help but panic. So it's happening at last. He's always wanted to have a date with her. But he's got zero experience in that department; he won't know what to do.
If the date goes well, maybe, he could take things to the next step. Although his chances are low, very low and he knows she's waiting for that guy to return. He can't control himself anymore. It's not like he loves her in that manner, at least that's what he thought. But Andrew wanted the relationship between them to work. If they were both in love with each other, wouldn't that be better?
