Please recommend wedding venues with a view in South Korea.

Hello! I am looking for a beautiful wedding venue in Korea with a view of the mountains. I am open to anywhere in Korea, as my partner and I met here. Since then, we have been captivated by the mountains and nature of Korea, and we want to include this wonderful scenery in our wedding. I have searched the internet, but I am having difficulty finding the perfect place. I would appreciate recommendations for venues where we can hold our wedding against the backdrop of Korea's beautiful mountains and nature. Thank you for sharing various ideas and information. I look forward to your advice on places you have experienced or know about. Thank you!
