Valentine's Day is not just a day for couples, but also for K-pop fans to share their love for their favorite groups.

Prior to Feb. 14, fans of the popular K-pop group 2NE1 (Blackjacks) began submitting and uploading "love letters" to the YG Entertainment group.

"Dear Bom, CL, Dara and Minzy," wrote WeLoveBom on Friday.

"We miss you dearly. Thank you for all the great and lovely memories so far and I hope we get more in the near future. Thank you for existing in our lives, the good music, the great performances, everything. Good luck to all four of you in your solo ventures!"

Reportedly, CL has returned to Korea after spending part of January and February in America to prepare for her solo debut.

The female rapper is rumored to be working with Sean Garrett, Diplo, Skrillex, Florence and the Machine, among others. Her debut will be overseen by talent manager Scooter Braun, known for working with Psy, Justin Bieber and Ariana Grande. Recently, CL also confirmed her appearance on the Black Eyed Peas' 20th anniversary album.

Meanwhile, Dara is preparing to begin filming for the web drama titled "Dr. Mo Clinic" alongside model-actor Kim Young Kwang.

"Since it's my first drama, I'll learn and grow as an actress from now on," said Dara according to allkpop.

"I think this drama is a very good opportunity for me as I can meet fans around the world online through this new genre of web drama. The character is very interesting as she's so similar to me. Of course, I feel somewhat nervous and burdened, but I will concentrate and work hard."

2NE1 fans are also eager to see Park Bom return with her own activities. She powerhouse singer has remained out of the public eye domestically and online since last summer.

"Bom, we are waiting for you, CL, Dara and Minzy," continued WeLoveBom.

"We are rooting for you! We love you lots [and] I hope we can see all four of you together soon!"
