shoyo(you) and kageyama were best friends... but with time they stopped fighting every day, but... they got more, more close... almost... too close, like intimate. It was now obvious that they felt something more than just a friendly feelinf for each other. But they still didn't realize it...
it was Christmas holidays... shoyo and kageyama planned to pass it together. They were still at first year of karasuno high school... so they didn't had the money to buy a room in a hotel... so. Shoyo's family was out, shoyo's mom and dad were out for work, and his little sister was with them... so. Shoyo's house was free until new year. They decided to stay here to pass their holidays, Christmas, New Year's Eve... but. the first day of holidays was kageyama's birthday, though... shoyo didn't know, because kageyama never told him.
