To all STAR1 who always love and support SISTAR. Hello, this is the leader of SISTAR, Hyorin. It's been 7 years since SISTAR debuted. The time I spent as SISTAR's Hyorin and my fans was very valuable and could not be replaced by anything. It's all like a dream. At this time SISTAR members will walk towards their respective directions for our second life. I want to thank sincerely to our fans for being able to let us know how happy and fortunate to be able to sing, be on stage and be loved and loved by everyone. We put aside sadness and support each other's dreams and will work our best to grow in our world. The members and STAR1 that I love, you will remain forever in my heart. STAR1 is very valuable and always gives me love and lots of strength even though I still have many shortcomings. Thank you most sincerely for you. I love you all.

I once told fans that we must be happy and I hope you are all happy to have spent 7 years with us. The time I spent with STAR1 and SISTAR members was very happy and valuable. I don't think I will be able to show my sincerity to many people as I tried and my regret is that I can't do the best for you as SISTAR. When fans told me that they were getting strength from my cheerfulness, I became stronger. I will not forget that and will still be stronger. Even when I'm menlis, I have a lot of memories. Now the members have agreed to support our respective paths. But it's not that we won't meet you again, so I will work hard as a better Yoon Bora from now on. All STAR1 that I love and people who love SISTAR and Bora, I am very grateful and happy because you are always with us. So let's always be happy. I love you ^^.

It's been 7 years and I think I'm very happy during this happy time and getting better at a difficult time because there are SISTAR and STAR1 members who are always near me. When I looked back, I was very sad and sorry for not being able to spend a lot of time with our fans. No matter where I stand now, I will not forget this feeling to our members and fans. I love you guys, I'm sorry and thank you. I'll give you good music. Come on, we're all happy to get to the last moment.

Hello everyone, this is Dasom. It's been a long time and I have a lot of things I want to say but I'm worried about how to start. It's been 7 years since SISTAR debuted. First I want to thank the fans who always support and love us for that long time. I think I won't be happy and finish 7 years with you, because that can be very difficult. I am also motivated to develop because of all of you. This is indeed sad, but SISTAR has decided to split up after the album is finished. We receive a lot of love as SISTAR and we want to return it little by little from now on. I will try to communicate more often with fans from now on. Please always support us and thank you.

Thank you SISTAR We Are Miss you are.
