Perfect chemistry

The couple decided to finish up their work so they would have time to watch a movie or do some other fun activity. They were quite disciplined; they sat in the same room, but they each did their own work and only conversed if it was related to work. It was much more effective than they had expected, especially since they ended up helping each other solve a few issues. 

By the time they were finished, it was already 2 pm. Leo shut his laptop and stretched his limbs. "I'm suddenly starting to think that if we didn't meet sixteen years ago, we would still end up together."

She frowned as she arranged the documents she had finished reviewing. "Why would you suddenly come up with such a strange thought?" 

"Isn't it already so obvious?" He grinned. "With our level of compatibility, even if we didn't get together because of love, we would be a perfect match for a business marriage, don't you think?"
