First solo travel in South Korea

Hi everyone, I'm a french woman and I'll go to my first solo travel in South Korea at the end of september, i'm a bit anxious because i'm an introvert, i've already been to the country in 2024 with my partner and i'm learning the language ( kdrama fan here 😄 ). I don't know what to expect as a solo female traveler, and i'm scared to get bored. My first week in Seoul I manage to enroll in lexis korea to have in the mornings korean language classes, and on the afternoon i'll explore Seoul, still don't have any precise details of what i'll do, and in the second and last week of my trip I will go to the south of the country, not Busan because i've been there already. Can you guys give me tips and advices as female solo travelers ? Thanks 😄
