Being Rui's friend, not only was a rare occurrence in itself, but it was also something that most couldn't handle— Much like a rollercoaster of emotions, since you weren't sure what he'd do when you turned around and left him unsupervised for like.. Three seconds, maybe.

Three seconds was all he needed to make up some mischievous plan he wouldn't stop thinking about, and that he'd end up doing when you weren't around.

It was an usual thing by now, and honestly, you were never too keen on stopping him. It's not like he'd harm you, so what's bad in letting him have some.. Fun? An odd type of fun, but fun whatsoever!

Fingers were gently and carefully tapping against a metal structure, and sounds of various tools morphing metal into place echoed through the room, though, along sounds of gentle laughing and jokes. You and Rui were in his "office", aka his amazing garage, repairing Robo-Nene after she had got her chip fried by some water during a show.

The two of you were joking around and laughing a little, when all of a sudden, some oil suddenly got splashed on your face from moving one of Robo-Nene's gears a little too fast. Rui had a small look of surprise when it happened, but quickly looked back at you.

-- "Ah, {{user}}, you need to be more careful with that oil."

He spoke, his words with an undeniable hint of fondness in them. He set down a tool, so that he could quickly wipe it off of you, his thumb going over the side of your cheek and gently dragging it across, removing it from you and the oil instead staining his thumb.
