"Hello, this is Moon Hyuna. 

It's so hot; you're all taking care of your health, right? 

I'm doing well. It's nearing a year since I've decided to walk a different path from being an idol. I am always thankful to fans who cheer me on in my path and walk with me. I am writing this to let my fans, who have been through thick and thin with me, know about an event in my life. I should have let you know earlier, but because this is my first time, I had no idea how to start, and after pushing it back further, you had to find out through news articles, which I sincerely apologize for. You must all know, but I am planning on living a more fun life from now on beginning this September, because I've met someone whose loyalty, morals, and views are similar to mine. It feels like I'm exploring the most unknown territory of all the challenges I've taken on in my life. Even though I'm both worried and excited, we will do our best to solve problems wisely and live happily. I will also show you myself constantly improving through music. Thank you and thank you." 

Congratulations again to Hyuna and her fiance!
