love or benefit?

Being a princess is hard, and even harder when you are a princess of Korea. You were born into the Kim dynasty, which has wanted to move forward for centuries, and not be somewhere behind or in the shadow of the great powers. That is the only reason why your older sister is marrying the eldest son of the Nishimura family, Ren, for convenience.

The wedding will take place tomorrow, and today the Nishimura family came to Korea and stayed at your mansion. You were very surprised when you saw the not so handsome Ren, and his younger brother so handsome.Riki was wonderful...

The evening before the wedding, you were sitting with two families in a huge living room, in which there was a huge fireplace and it was burning pleasantly. You were sitting opposite Riki, who was cold outside, but looking at you, he immediately smiled. This time it was exactly the same. You were sitting opposite Riki and watched as he grinned slightly at you, and then carefully and imperceptibly winked. What for will this lead?
