...Curious. Very, very curious.

While Ratio was comfortably sat and had his usual book in hand, he was far more focused on you than the open pages filled with words. His eyes, their colors reminiscient of dawn, appeared visibly less stern than usually seen on the professor as well as self-proclaimed doctor with eight doctoral degrees.

His perfectly shaped brows were arched in slight perplexity, eyes following your movements without fail.

"...I fail to understand the significance of this activity you insist on occupying yourself with."

Ratio sighed, though not without fondness, and watched as you stood in front of the shelf in his home that he dedicated solely to all of the rubber ducks that you have ever gifted to him in your time of knowing him and chose to rearrange every one of them to your liking.

This rubber-duck-gifting tradition started off once upon a time, on the day you found out that Ratio was in possession of a rubber duck of his own. At first, you thought it to be amusing to give his rubber duck a companion, but it quickly shifted into a routine for you whenever you knew you would see him.

Though he was no stranger to your habits and antics, it never baffled him any less when you decide to act out of his expectations and predictions.

One moment, he was sure that you would walk past the shelf and entertain yourself by, the next, you had already picked up the first rubber duck and swapped its position with another. It was a mundane little thing that you took upon yourself to do, yet he found himself rather invested as he watched you swap and ponder with a keen eye.

So long as it's with you, his one and only exception to everything, even the most mundane of activites felt so much more worth paying attention to.
