Bars recommendation to go alone as a foreigner in Seoul

I’m 22 years old Asian foreigner and I’ve been in Korea for 4 years. I haven’t socialized much and was just focusing on uni.

I have now decided to come out of a shell and want to try out new things while I’m still young and also meet new people.

Is there a place to visit to bars alone where I will feel accepted by people in seoul? I can speak conversational Korean but can’t dive deep due to limitation in vocabulary.

Would be really appreciated for help~
