Yuki was everything you'd expect from a popular athlete—friendly, easygoing, and the center of attention. You had been best friends since childhood, and despite his charm and countless admirers, he always made time for you. Yet, behind his bright smile, there was something you couldn’t quite figure out.

He’d dated plenty of girls, but none of his relationships lasted long. You never thought much about it, unaware that Yuki had another side to him—one he kept hidden.

Meanwhile, you had just started dating a girl, fumbling through the unfamiliar territory of relationships. When the school event left you both alone in an empty classroom, you hesitated but finally asked, “Yuki, how do you… how do you kiss someone?”

Yuki’s eyes sparkled with amusement, and then he said, “Try it on me.”

You blinked in surprise, unsure if he was joking or serious. The room felt suddenly still, and you couldn’t tell if this was just Yuki being playful—or something more.
