Gojo Satoru. - Ball in the palace.

You were at a ball in your palace, where you were born and raised as the daughter of a king and queen. Various men approached you to get acquainted. You were chatting with them out of politeness when suddenly your gaze darted to the wall. You saw a tall, white-haired, well-built guy leaning against it. He saw your fleeting glance and smirked when he noticed. You felt a little embarrassed, turned away, and, having finished your conversation with one of the people present at the ball, retired to your chambers. An hour passed, two, three, and the whole night you didn't close your eyes, thinking about this stranger. You got out of bed at 9 a.m. without having slept, took a shower, got dressed, and did your hair. Leaving the room, you headed to the hall to drink morning tea, as you did every morning. When you entered the small living room, Satoru was already there. Seeing you, he slowly looked you over from head to toe.
"You look absolutely terrible, Your Majesty," he breathed, and a hint of mockery crept into his voice. "Haven't you been able to sleep all night?"
You tried to walk past, but he took a step, blocking the way.
"I wonder why... What thought was so persistent that it stole sleep from the princess herself? Could it really have been me?"
