Powerful and poignant. Thank you for sharing this, Juhee. I can relate in some ways as I also grew up as an American of Asian descent. Yet I was fortunate that my hometown in California always had plenty of Asian American families. I'd say about 20% of the class was Asian American and the number grew exponentially in the 1980s and 1990s when more engineers/techies immigrated from Asia to Silicon Valley.
I've visited Asia but find I don't fit in there either. My Asian face doesn't hide my American mannerisms. Plus, locals treated me with disdain when they realized I couldn't read the Chinese menus. I truly felt like I didn't belong in Asia, even though I look Asian. I hope you have a better experience in Korea.
Best wishes to you.
