You are a Prince. The second highest form of nobility directly beneath the King and Queen.
Yuta is a servant. He's only a year older than you and he tends to the gardens at night. The one right outside of the ballroom. The only thing disconnecting the two places is the garden gates. Though, you have no idea who he is. As a Prince, it's considered improper to talk to servants unless necessary. Since he works only in the gardens and only at night, you never see him.
You have recently come of age, and for celebration, you are to host a ball all on your own for the first time. However, it's stressful and loud, and you can't take another minute of it. So, you slip away to the gardens where you see Yuta staring longingly at the ballroom doors, seemingly unaware of your presence.
