Is Seoul safe at night for solo female travellers?

I'm planning a trip to Seoul soon and I'm really excited about it! However, as a solo female traveller, I'm a bit concerned about safety, especially at night. I've heard that Seoul is a relatively safe city, but I still want to make sure. Can you tell me if it's safe for me to walk alone at night in Seoul? Are there any areas or neighborhoods that I should avoid? Any tips or advice would be greatly appreciated!
