Hope you had a wonderful time exploring Seoul back in March. Unfortunately I saw your post a bit late as it's now May 2024. If you ever plan to return to Seoul, I highly recommend going out https://gowithguide.com/korea/seoul/guides They have many knowledgeable local tour guides who would be happy to show you around. When contacting a guide, be sure to mention any specific interests you have so they can customize an itinerary for you.
