Summary: This is their mania –their obsession, their enthusiasm, their craving. Nothing and no one can stop them, not even themselves. Not that they really want to stop, that is. Warnings: Kageyama/Hinata, drabble.

Disclaimer: I do not own Haikyuu. This is my first story for it. I'm doing this for you Little Fangirl1! Happy Birthday!

Compulsion

It was strange, neither of them knew when it began but all of a sudden there was this itch, this need, this… something.

And here they are today. The winter sun has already set and both of them are now heading back home, hands in gloves hiding in their hoodies pockets.

Breathing heavily into the bright orange scarf the shorter of the two is glad to hide behind said scarf to smile without fear. Sure in this weather it would have been safer to ride his bicycle to school and back but then he wouldn't be here now side by side with his taller companion.

Unknown to the shorter companion the taller boy is also very happy that he "forgot" his bike.

Though they say nothing on it –it is very obvious to both of them that neither forgot a thing. Especially since this is the eighteenth time this month alone the two are walking side by side on their way home.

It is silent. The winter has scared all the birds away, with the exception of two crows.

They walk in pace, each one keeping the other from pacing to fast, even as both wish to get there as soon as possible.

And there it is: the gates to a park. In the summer their favorite place to train. Now cover in snow and abandoned by most it is their sanctuary.

Without a word, without a thought –their hands, though gloved, grasp one another.

It started in the spring. By accident. At least that's what they tell themselves: Hinata's natural clumsiness combined with the park's natural dirt ground constantly sends the young volleyball player home in cuts and scrapes. That's why poor but responsible Kageyama has to escort him through the park to make sure Hinata gets home safe and sound. And holding hands makes it easier to not lose the shorter player in the crowd.

There is not another soul in the park. Not a bird, not a pet, not a person.

Their hands still do not let go. Neither even bother to try and separate their hands from one another.

It's just a habit now –they'll argue if questioned about it. Feels weird to do everything else the same but not this one little part of the routine.

They of course don't tell anyone about the time Hinata held Kageyama's hand when he fell asleep during the drive to the overnight game. Or the time Kageyama drags Hinata away from his class by his hand and even when they get to the gym and have to change from practice still doesn't let go –even though its they'd have to in order to practice in the first place. Or how Hinata refused to let go of Kageyama's hand after they find a love letter in the taller boy's shoe locker.

But still –almost a year into the 'accidental' ritual –neither boy wants to confront its meaning to the other.

And that's okay.

Holding hands now is just as natural as breathing, seeing one another in their dreams, or syncing up during a game –so why should a compulsion be a bad thing?

AN: Good News! My short hiatus for the end of semester did not affect this story! Yay! Celebrate! See you all next year!

See you all next month and year with:
