I am preparing to study abroad for graduate school in Daegu. What are the differences between Seoul and Busan?

Hello! I am going to Daegu for graduate school and am about to start a new life. I have visited Seoul and Busan before, and I found Busan to be relaxed with friendly people, which left a very comfortable impression on me. However, I have not been to Daegu yet, so I am curious about it. I would like to hear from those who currently live in Daegu or have lived there before. What is daily life like in Daegu? How does it feel different compared to Seoul or Busan? How do the people of Daegu generally treat international students or foreigners? What do you like about living in Daegu, and if there is any information you wish you had known before moving, I would appreciate it if you could share that. I look forward to your advice!
