"It's February 21 again.
As a member of MAMAMOO's team, many people congratulated me not only on my birthday but in any situation. I'm having a very happy day. I've told you a lot, but I'm worried that I'm getting this much love, but I'm also very happy. I think that I have to repay you for this great love.
I'd like to say thank you again to all the people who always support me, encourage me, love me, and care for me.
When it's my birthday, I'll be able to show you something and give you something special because it's my birthday. I'm so excited and looking forward to it. That was a long rush.

When I meet a lot of fans, I hear a lot of bright and fun stories, but I hear a lot of stories of people who are tired as well. I don't know how to comfort you when I hear that. I don't know if my consolation will be... I have a lot of thoughts. Everyone's having a hard time.
This song is about my experiences when I'm tired or exhausted, and I lie down in the evening. I organize all kinds of thoughts, and sometimes I get emotional as if I were on a rollercoaster with just my thoughts. At the time, I made this song with the hope of comforting you.
In the evening, you get more emotional. Of course, it's good if it's good, but unfortunately, sometimes it's not.
I can't comfort you with this song, but I want to comfort you with this song so please listen to it comfortably.
The title is 'Listen to this Tonight', but it's okay if you listen to it during the day too.

Finally, thank you all."
