Sunghoon and Niki are sworn rivals. They hate each other so much that they would rather kill themselves done admit that the other is even slightly good.

Sunghoon was always the more sassy type, the one who was quiet but witty with his words meanwhile Niki was the loud, arrogant a little typa guy who knew just how to rile people up.

They had to travel to a school trip together. Niki was excited. He was really excited. It had been long since they'd gone to a trip to the mountains from the school. He wanted to enjoy with his friends— afterall, it was less that they got to rest.

A week of delight. A week of savoring the air of coldness and snow. Niki was so ready. Except when he reached his assigned seat on the bus which everyone was supposed to travel 18 hours in it— yes, that travel comfy buses— his bus partner was... None other than... Park Sunghoon.
