"Hello, this is Karina. First, I am sorry for surprising you so much. I (wrote this letter) so late because I know many of you were also surprised and I wanted to be cautious. 

I'm well aware of how disappointed my fans must have been and how saddened they must be recalling the conversations we've had together. I feel deeply sorry because I understand those feelings all too well myself.

With the hope that some of these feelings can be conveyed, I decided to write this letter. Despite my concerns about causing further hurt, I write this because I wanted to convey my heartfelt apologies to the fans who have given me the warmest winter from the moment of my debut.

I want to make up for any hurt MYs (aespa's fandom) have experienced. I have always been sincere to MYs and you continue to be precious individuals to me. 

Thank you for reading this letter, which can be too short to convey my feelings. I want to assure I will not disappoint you in the future and continue to show a more mature and diligent side. Please keep watching.

Please take care of yourselves and don't miss meals, MYs. I'm sorry and thank you so much."
