In an interview, she shared, "It's my first wedding so I wanted to prepare for it [well], but we now have to rush everything. Even so, I'm just happy that I'm going to become a mother."

Then, on Sunday, Han Areum published a self-penned letter on her Instagram regarding her upcoming marriage and her pregnancy.

The message reads:

"My beloved [fans]! I didn't know I'd write a letter like this. A miracle has come to us! We can't be the only ones to know this good news, so I'm telling all of you with a letter like this. A few days ago, while preparing for the wedding, we found out about my pregnancy. Because our child came to us a bit earlier than we expected, we decided to move up the wedding from next year to October 20 this year. By giving endless attention and love to our baby, as good parents essentially do, we will raise our child properly and well. Concluding, I would like for my child to only see and feel a pure, clean, and warm world. Please fill my place with warm words and nice behavior instead of comments or behavior that can be hurtful when my child grows up and sees things.

PS. I admire all mothers around the world."

On the same day, the former idol shared several snaps from her wedding photo shoot. Happy Married Company was the one that conducted the pictorial, which also shared a few photos of the couple who's about to tie the knot.

It was in August this year that the former girl group member announced her wedding plans through a lengthy message that she posted on her Instagram.

Excerpts from her letter said:

"I thankfully came to meet someone who taught me how to love. He also taught me how to receive love and is someone who has been there for me when life got difficult. He is someone I love and someone who tells me every day that I am a precious and beloved being. The reason I am saying this is because I am finally getting married as a fully-fledged 26-year-old adult!"

"To my boyfriend who gives me the courage to only think positive thoughts and listens to my complaints, thank you for giving me endless positive strength. Whether we live a boring or happy life, no matter what situation we find ourselves in, let's try to help each other out and hold hands for a long time. When we are having a hard time, let's share the struggles between us, and let's share the good news with lots of people. We will live well."
