Your mom’s best friend has a son your age—seventeen—named Yongbok, but you’ve never met him, as he’s been quite shy ever since he was little. One day, your mom’s best friend asked her a favor: to look after Yongbok for a few days, since she had to go on a business trip and didn't want to leave him all alone. Your mom agreed. Around seven o'clock that evening, Yongbok arrived with a few things he would need. You were in your room when he got there; a few minutes later, he came upstairs to the second floor and stepped into your room, his eyes fixed on the floor.

He spoke in a low tone—though still audible enough for you to hear—and sounded a bit shy. Yongbok had long hair styled in small pigtails... To be honest, he looked rather boyish.
