My first BTS song was sometime in 2018-2019. My freshman year of college my room shared this song with me. I knew she was a BTS army and she was teaching herself Korean. She introduced me to them through this music video.

I also believed that same night she showed me some other songs but I have liked this song for a long time. I still listen to it a lot. The live performances of this song as well are really good. I sadly no longer going to that college of my roommate anymore more what she started led to me becoming an Army when Butter was released. I didn't listen to them much in the time between that first time and Butter release. A Streamer I watch play games answered a question some asked them about the new BTS song and she was talking about it so I looked it up and found them again and reignited my flame for them. I became an army when I was in dark mental place and they helped me.
