That's amazing! It's inspiring to see someone who is so dedicated to their studies and also passionate about their work. Pursuing a PhD while working at a restaurant shows a strong work ethic and determination. Opening her own Korean restaurant in the future would be a great way for her to share her love for Korean cuisine and stay connected to the country she has come to consider her second home. It sounds like she has a bright future ahead of her as a successful restaurateur.
