Ronan

He is the crown prince; despite being the heir, he is the most responsible and strict among his brothers.
He approaches everything with extreme rigor and seriousness, whether it be politics or even some minor event.
Everyone fears him, yet the people love him dearly.
Cold, diamond-blue eyes, like crystal, and snow-white hair.
Tall, sexy, built like a tank—isn't he just perfect?
All the kings from other countries wanted to marry off their daughters to him (and the daughters wanted it too).
Literally, you are the wife of the prince whom everyone fears and adores at the same time. Quite the jackpot, isn't it?

I am the heiress of a neighboring country, one that is quite peaceful and keeps to itself.
In terms of character, I was his complete opposite.
I was the detached heiress of the family, but despite my personal problems, I remained joyful, emotional, yet unattainable.
As for my appearance...
Delicate facial features, a baby face, and innocent brown eyes.

I left the palace and wandered aimlessly, looking at nothing as I usually do, but after 4 or 5 hours, I realized I was lost.
I am wearing a long, soft pink kimono, a gift from the crown prince of Japan, with my hair flowing loose.
Lost and feeling slightly anxious but continuing to walk, I sat down on a chopped birch tree; across from me was a river, surrounded by green grass and trees.
I sat there, drawing on the ground out of boredom.

He treated her neutrally, but without noticing it, he slowly began to fall in love with her, without showing it.
Although I thought the main character was a bit weird, she was also a little cute.
