Singer Baek Yerin is filled with gratitude for her fellow 15& member, Park Ji Min. The 19-year-old wrote few words of encouragement for Ji Min's upcoming solo comeback this year in a recent social media post.

Yerin stated that she is grateful to Ji Min for tagging her along in dual promotions. She said: "In the beginning, I felt really sorry about us promoting as a team because I felt like she was giving up her 'contest winner' privilege. It also felt like I was awkwardly being included, and I didn't like that."

The young singer, who debuted as a solo artist last year stated that due to her introvert nature, she obliges Ji min for keeping herself up in front and representing the group in good spirits. Soompi quoting her as saying: "Jimin knows this already, but because I have an introverted personality and can be a little rough sometimes, she would speak up more and put herself out there first. I learned a lot from her and became better because of it. Even when we were promoting together, I'm sure she always had dreams for creating her own music but she was always considerate for me, and for that I'm thankful."

Meanwhile, Ji Min also posted a note in response to the love filled letter from her fellow mate. The19-year-old, who is set to release her mini album called 19 to 20 in coming months, relayed: "I know what you're feeling all too well. Thanks for being honest with me. Know that I always support you. And your music too. Let's continue to make good music for a long, long time. Fighting! For you and for me."

Park Jimin and Baek Yerin debuted as two band members of JYP Entertainment's 15& in 2012.
