Yoon Sangah Birthdate: September 04, 2002 She is the cool rapper and lead dancer who likes baseball. She is the oldest in LIGHTSUM. She is cheerful and thoughtul. "Among the various flavors of ice cream, Vanilla is the most basic flavor. It also means that the eight of us will create a richer flavor emitting charm as different toppings on the top of the vanilla. Each member put in gestures or points that show their own feelings. I think it will be a good to find the killing point that maximize each person's charm and enjoy it together. It's a song that makes you feel better the more you listen to it. Anytime is fine, but play 'Vanilla' loudly, especially on gloomy days or when you're especially tired. Your firm heart will melt away a little. I'll continue to give you strength with good music.
Han Chowon Birthdate: September 16, 2002. I want to thank all the members for supporting and waiting for my debut. Thanks to the warm words, I was able to cheer up and reflect on my will. It sounds cliche, but I worked really hard on it. As the main vocalist, I tried hard to express the team's color with a firm voice. In terms of vocals, I have a desire to try various genres. I want to be a vocalist who makes listeners feel and share various emotions, not just singing well. If I have a chance one day, I want to act in a drama or musical based on my experience in movies before my debut. If you build and expand one by one, you'll be able to stand tall as LIGHTSUM, which is loved by many people, and Han Chowon."
Kim Nayoung Birthdate: November 30, 2002 The second main vocal of LIGHTSUM with cute and lovely appearance. She said, "It hasn't been long since I've been in front of you, but I think I need to work harder and do better as much as you've shown interest in me." We'd like to show our various charms through various opportunities. Personally, I want to do a reality show with the members. You'll be able to see a different side of us from the stage. I hope we can go somewhere together. We've never traveled together yet. Our first goal is to promote our music to many people. And if I get more greedy, I'll dream of making a lot of impression this year. We'll be a group that's recognized by everyone and not ashamed of its recognition!"
Nagai Hina Birthdate: April 7, 2003 Her clean voice is attractive. Her innocent appearance and smiling eyes are cute. She’s the only Japanese member. "I'm not saying this formally. Even though each of us is very different, it's fascinating that we get along well. Looking back, it's not that long that the eight of us have teamed up. I met my friends who were working hard and preparing for each other. Maybe because we had the same dream, we were able to melt into each other quickly. In the process of getting it right one by one, I tried to be as honest as possible and talk a lot. Especially because I don't have enough Korean, I sometimes can't express it properly and sometimes I don't understand the situation perfectly, but the members help me a lot. I hope we can be good friends who fill and lead each other like now."
Lee Juhyeon Birthdate: April 8, 2004 She is the leader and main dancer of LIGHTSUM. She’s been praised by Rain at the age of 13. She's a dancing machine. "Debut. Honestly, I'm still surprised and nervous. During my 7 years as a trainee, my debut that I thought was just around the corner was canceled and I was frustrated that there would be no tomorrow. Even after the release of the debut schedule after recording the album, I felt anxious. Now that I'm on stage, I want to sing and dance to my heart's content and meet you in various ways. We haven't shown you much yet, but thanks to all the support and expectations, we're very happy and proud. We're going to think more and work harder to find our own color. I want to be a group that continues to grow and develop with you, like close friends.
Lee Yujeong Birthdate: June 14, 2004 Sub-vocal characteristic, which combines innocent aegyo and sweet voice, caught the eye with cute looks. "Vanilla" is like a sweet heart. It's our story, and I think the rhythm and cheerful atmosphere will go well with this season. There are a lot of variations, and there are many fun elements hidden, so it'll be fun to listen to. Please look forward to our sophisticated dance performance. I hope the special, thrilling vanilla flavor of Lightsum will be a magical gift for your normal day."
Oh Huiyeon Birthdate: August 1, 2005 My team's biggest attraction is that I can't define it in one word and one color as the attractive dimple owner with a quiet but solid sub-vocal characteristic with figure skating skills. In the future, we're going to show you a wide range of music and styles by trying various concepts. This song is refreshing and cute, but we're confident in everything from innocence to girl crush. We can do powerful group dance perfectly. We will continue to show new music and charms without setting limits. No matter how hard it is to practice, it's our strength to laugh and enjoy it. I'll do my best to deliver that positive energy on stage."
Kim Jian Birthdate: November 4, 2006 Her position is rapper and sub vocalist. She is young but not young. Her group name is 'LIGHT' and 'SUM'. Just as small light gathers to form the world, eight of us gather to become light and deliver positive energy to people. I liked it since I first heard it. The meaning of 'more' is especially meaningful in that it keeps filling in something. I think it goes well with our goal that the members with different colors will meet and shine. I just want to show you the best of my name."
