"Hello, this is Chen. Are you staying healthy and well these days, with the temperature differences widening day to day? The hot days have moved on and it is now a warm fall.
The reason I am writing and greeting you through this letter today is to let you all know that I will be enlisting for my mandatory military service on October 26. I will fulfill my duties diligently while taking good care of my mental and physical health, so that I can grow as a person during this time away and greet you all with a better image; I hope that you all will continue to live beautifully and healthily like always!!
Thank you always, and I love you."
