On March 18, Jessica uploaded a new video on YouTube titled, 'My Firsts'.
One of the things that Jessica talked about in the video was the time when she saw Krystal for the very first time.
She went on, "So, the night before she was born, my parents suddenly dropped me off at my aunt's place."
Jessica said, "I knew that I was going to have a little sister, but actually seeing her felt strange and cool at the same time."
Jessica laughed and said, "It was because I was the only child until then, and I got the feeling that my parents' love was going to have to be shared with her from then on."
She added with a smile, "But now, I'm so glad that I have a sister, not brother. Mom and dad, thank you."
