Get a proper understanding of popular local cultural works. You can ask your date to make recommendations, so you can increase the topic, learn about his tastes, and learn English. When I was dating C, I often felt a lot of anxiety about English, and I mentioned to him that I didn't want to learn English at all if it wasn't for dating him (it's really important to find a handsome and interesting date). Therefore, I began to study the expressions in "Normal People" frame by frame, which is very Irish, and it is also very practical and suitable for the daily life of studying abroad, and I began to read English novels.
