Red Velvet's Yeri has unveiled a new, dreamlike teaser image for her 'SM Station 3' single - "Dear Diary". 

Composed and written by Yeri herself, "Dear Diary" is an acoustic ballad genre. Yeri said about her song-writing process, "I was asked so many times what I expect to change once I turn 20 years old, and I started writing this song as I felt anxious and stuck. I still have a long way to go, but I've learned how to take care of myself both inside and out by now, and I put in the words that I wanted to say to myself now that I've endured 20 long years and reached a very special age." 

Yeri's "Dear Diary" is set for release on March 14 at 6 PM KST worldwide!
