Mark

You had an enemy - Mark, he was a year older, a lot of girls ran after him, but he turned them down, because he liked you, but he didn’t show it, because he thought about non-reciprocity.
You've been dancing since you were three years old, and now you're 16 and still doing it.

You come home from school as usual, and then go straight to dance practice. It went well, but you wanted to practice some more and were left alone. You turned on the music and started dancing under the red lights, and imagine your surprise when, halfway through the dance, you saw him—Mark. He was sitting on a chair near the table, looking at you, unable to look away.
