How can I make friends in Seoul?

I've been living in Seoul for about 5 months now, and I really enjoy life here. I especially love the energy and food of this city. However, I find it a bit disappointing that I lack social connections outside of work. I live in Hannam-dong and plan to stay here for the next few years. I am in my early 30s and would like to make friends with people of similar age. Nationality doesn't matter to me. I would like to meet people who enjoy casual jogging, hiking, cycling, having a cup of coffee, engaging in light conversations, and occasionally doing fun activities together. I'm curious to know how those who have had similar experiences have built their social networks. If you have any tips on communities, events, apps, or specific places where I can meet new friends, please share. I would love to hear about your experiences and advice. 🙏
