Jessica talked about her sister Krystal in an interview with Xports News.
The singer recently made a comeback with 'My Decade' in celebration of her 10th-anniversary. Many questions were asked regarding Jessica's new album and one asked if she made Krystal listen to all of her songs.
Jessica answered, "Of course I did", and revealed, "Krystal said the title song isn't her style. She tends to like things that are not the mainstream. She actually liked the song 'Starry Night' I dedicated for my fans. She liked it so much that she asked me if that song could be the title track instead."
