■'Find My Color Flavor.' CM Story
In this first-ever TV commercial appearance for the VIBY members, the ad vividly portrays the fresh, yet-to-be-colored artists discovering their own unique colors, set to VIBY's new song 'HANAMARU' and accompanied by the refreshing sensation of flavored sparkling water. Under the message 'Find My Color Flavor,' the commercial combines the multifaceted charm and infinite potential of the VIBY members, who are on the cusp of their official debut, with the flavor lineup of CRYSTAL SPARK. Through a story that encourages viewers to find their 'oshi' (favorite color), it expresses the brand's worldview of adding color to everyday life along with the exhilarating fizz of strong carbonation.

■About the CM Song 'HANAMARU'
The song used in this commercial, 'HANAMARU,' was released as their 2nd Digital Single on May 13. It's a song filled with the wish that everyone—on good days and bad—gives themselves a 'HANAMARU' (a flower circle mark used for praise in Japan), just like the first one everyone experiences. It's a youth anthem packed with VIBY's true feelings. The music video was shot in an open space with a blue and green color palette, based on the mood of a European boy in spring, highlighting VIBY's energetic dance performance.

■Making-of Video & Filming Interview
The making-of video captures the five members dressed in refreshing outfits inspired by the image colors of each flavor, like ramune and grape soda, filming under a blue sky. The synchronized dance scenes, with their sharp moves and youthful smiles, are captivating. The video is full of scenes that show the members' close bond, such as them huddling together and laughing in a cheerful, friendly atmosphere. The solo cuts are also noteworthy for their diverse expressions that highlight each member's charm, including calm looks and careful gestures.

Q1: What are your thoughts on your first TV commercial shoot?
RENKI: The most difficult part was filming on the rooftop. The sunlight was stronger than I expected, and it was hard to keep my eyes open. The most fun part was when we all danced together at the end, formed a huddle, and encouraged each other, saying, 'Let's give it our all for one last take!' That was fun.
AKITO: I'm not good with the cold, and since we were wearing summer outfits for the rooftop shoot, it was tough filming in the cold weather.

Q2: What do you think makes you 'you'?
KOTARO: I just started high school, so I think my freshness is my charm.
IO: When I sing and dance on stage, I pay attention to my facial expressions. I think my expressiveness during performances is what makes me 'me'.
RENKI: When I practice, I make sure to see things through until I can do what I've decided to do. I think that perseverance is my 'me'.
AKITO: Even if something goes wrong, I think positively about trying harder next time. I think that positivity is my 'me'.
RYOHA: I think being able to stay cheerful all the time is my 'me'.

Q3: 'HANAMARU' was chosen as the CM song. Can you tell us about the song?
IO: 'HANAMARU' is the second chapter of our story, following our debut song 'Mi*light'. It's a song about us learning to move forward with courage and positivity, enjoying the journey with our friends even when facing difficulties. We hope that listeners will also live each day positively and give themselves a 'hanabaru' for a job well done. The song has a fast tempo, and you should especially watch for RYOHA's rap part where we dance as if we're playing.

Q4: What did you think after actually drinking CRYSTAL SPARK?
RYOHA: It's really refreshing to drink when I want something sweet during a break from vocal practice. I recommend it!
AKITO: I like that it's zero calories but has various flavors and aromas. Since it's carbonated, it's perfect for when I'm on a diet or feeling hungry, so I drink it then.
