Prompt 25: You keep playing Christmas music, and it's driving me nuts, please play something else

He never intended to fall for him.

He never even intended to speak to him.

Ten years ago, Kaiba had walked into his class for the first time. He had not paid any attention to his classmates, he hadn't needed to.

He managed to last two years without directly having to interact with Jonouchi Katsuya, but then Yugi had obtained a blue-eyes and Jonouchi of course had to protect his little friend.

In duelist kingdom, Jonouchi was protecting his own pride. Challenging Kaiba to prove himself, he lost, but Kaiba had respect for him anyway, even if just a small amount.

His respect grew when battling the Big Five and saving Mokuba in the virtual world.

By Battle City, Jonouchi had announced that Kaiba was his rival. Seto hadn't cared too much, his sights were on the God Cards, but he did keep a watchful eye on the blond.

He did care, however, when Jonouchi almost defeated one of those God Cards.

Once again, he found himself in debt to the blond after saving Mokuba once again from the Big Five, once again in a virtual reality, once again without even needing to be asked.

He was stuck with Jonouchi and his friends then again with the motor cycle gang after duel monsters came alive and reaped havoc around the world.

In the grand prix, Kaiba had no time to even worry about the 'dweeb squad', but he did notice a familiar, highly accented voice cheering for him when he battled Sieg Von Schrodeor.

He didn't know why that made him smile.

After the pharaoh returned to his own time, he assumed he would never have to see the blond again past graduation.

But no, Jonouchi Katsuya was everywhere.

He competed in tournaments, he visited Mokuba, he even was taken on as a sponsored duellist by Kaiba Corp.

As time passed, Seto grew close to the blond, in the way rivals do.

They duelled, competed in other games and even competed in some sports against each other.

Jonouchi had become a part of Seto's life and the brunet had no clue how.

He also had no clue how he ended up dating the blond.

It may have been the tequila filled confession, or the blonde's warm lips on his own one night.

Seto didn't know, but he accepted it, as he did with everything to do with Jonouchi after that.

The man that once irritated him beyond all means had become someone he couldn't live without.

They eventually moved in together, got a dog and were horribly domestic, Jonouchi even ironically calling him 'dear' when alone.

The cooked together, cleaned together and slept together.

Seto never intended to fall in love.

But he did and he considered it a miracle.

He fell in love with a beautiful, strong, passionate man who loved him with everything he had in return.

Seto never intended for this to happen, but he couldn't imagine what his life would be like if it hadn't, and he didn't want to.
