Imagine your OTP as cats. Person/Cat A is a house cat, and Cat B is a stray cat. Now imagine them meeting for the first time.

OT3 Bonus: Person C is a duck.

Lucas was not the type of cat for going outside.

It was loud, dirty, too big, and overall dangerous.

His owner, Travis, has tried to get him to go outside, but never forced Lucas to do so, and was just fine with him staying inside anyway.
Kumatora, his owner's mother, was a little more set on trying to get him to go outside, but gave up after a year of having a stubborn house cat.

Lucas had to get some air sometimes, though. They had a large backyard with a little concrete area where the door was, so he would stay on that area and refuse to go to the grass where he would get dirty and it got louder and just everything bad.

And this is why Kumatora, Travis and Duster (a little family!) had no idea how he and Claus were brothers.

See, Lucas had an older brother (not older by much) named Claus.

Long story short, they were complete opposites.

Claus was an outside cat, and that already named all the differences.

Even though the older brother was a ginger cat (with darker orange stripes on his back and tail), it was almost like he was brown and green with all the dirt and grass that he came in with.

Lucas kept his yellow fur (with white splotches on, well, everything) spotless in addition to not touching the dirt.

It was a miracle to keep Claus clean for longer than a day.
But, onto the current day.

Currently, Lucas was inside, simply grooming his fur in the empty living room (The other members of his family were either out or in the other room) until he heard a faint noise.

His ears perked up and he looked around, stepping around on the coffee table and try to figure out where to look.

He heard the noise again and his curiosity peaked, he looked to the glass door that lead to their backyard and that's where he saw it.

Blue eyes met purple ones as a black cat with some white stripes in random places, including the tip of his tail, stood on the glass door, a little blue and red object on top of his head.

They just stared at each other for a moment before the cat outside slid his paw down the door and Lucas snapped out of it, padding over to the see through door and looking at him more clearly.

The noise had been the other cat's paw against the door, the blonde cat realized.

The black cat began speaking through the door. He sounded surprising clear, though still slightly muffled. "Hello! My name's Ness."

Lucas was slightly hesitant, but replied a few seconds after. "Hi... my name is Lucas." The words were mumbled, but just loud enough for the black cat-Ness-to hear.

"Oh, I like that name!" He said, smiling and looking past Lucas into his abode. "I take it you're a house cat?"

"Th-Thank you. And yes, I am..." He didn't need to inspect Ness any more before taking a guess. "And you're an outside cat?"

"Yup! Was it that obvious?" Ness laughed, and padded around the concrete area. Lucas wondered what it was like to wander around and not fear getting hurt or dirtied.

Speaking of... Ness wasn't dirty. Only his paws and his fur was ruffled, which was expected, but other than that, he was fine.

"Um, Ness..." Lucas started, getting the named cat's attention. "How come you're not extremely dirty?"

"Oh, that's easy!" Ness walked up to the door where Lucas hasn't exactly moved. "Since it rains pretty often here, there's lots of puddles, so I just go in those and I'm clean."

The blonde cat suddenly looked dismayed and slightly sympathetic. "You have to go deep in water? Don't you hate water?" Lucas gasped.

"Well, I'd rather do that than die of disease just because I didn't go into water for a few minutes." The black cat shrugged.

"You make a good point..." He said, and Ness looked like he was about to say something before Lucas' owner called. "Lucas! It's time to eat!"

The named cat's eyes brightened at the thought of food, but immediately didn't like the disappointed look on Ness' face.

"Sorry! I have to go eat..."

"When will you be back?" Lucas was surprised at the question that was asked so quickly.

"Oh...! I'll be back tomorrow, because after dinner I usually nap... but if you want, I can come here in about an hour."

Ness shook his head. "No, it's okay! I'll just be here tomorrow, don't worry about it."

"Oh... okay-" Lucas was cut off by a different voice.

"Talking to someone, Lucas?" The older ginger cat asked, his ears pointed up in interest as he walked over.

"Oh! Ye-" The little brother smiled at Claus and turned back to the see through door just to find that no one was there. "... No, no, no one."

Claus gave a suspicious glance to the smaller one before shrugging and walking towards the table. "Come on then, dinner's ready."

"Alright!" Lucas casted a last glance towards the yard before catching up with Claus to eat.
