On February 15, timelesz held an press conference to unveil the new members joining the group. 

As it was reported earlier, the new members are Shuzo Inomata (23), Daiki Shinozuka (22), Takuto Teranishi (30), Masao Hashimoto (25), and Yoshitaka Hara (29). They will be joining the existing three members (Shori Sato, Fuma Kikuchi, and So Matsushima) for future activities. Hara and Teranishi are joining from the actor division of STARTO ENTERTAINMENT.

At the end of the event, Kikuchi suggested a toast, saying, "I really want to do this," and the drink served was colored in eight different shades. It was revealed as a surprise by Kikuchi, Sato, and Matsushima that these colors represent the new members’ assigned member colors. Teranishi questioned, "Is this drink something we can actually drink?" as Matsushima explained the significance of each color.

Shinozuka, who was assigned the color "white," said, "I want to become someone who isn’t defined by any one color and can be changed by anything." He promised to focus on finding his own unique color. Teranishi, who was assigned "light blue," said, "I’ll do my best to live up to the trust placed in me and not disappoint those who gave me this color." He added that the drink's sour and bitter taste reminded him of the challenges of debuting.

Hashimoto was assigned "pink," and Kikuchi commented, "Masao is adorable but also has an adult-like sexiness." Hashimoto, who was surprised by the pink, said, "I never thought I would be pink! I expected something like light blue or a darker color, so I’m happy to buy more pink things from now on."

Inomata, who was assigned "yellow," explained it as representing "charm, being loved by everyone, and having a positive mindset without showing any negativity." He said, "I want to become the person So-kun said I should be." Finally, Hara, who was given "light green," said it represented "the warmth of the sun," and he hoped that this would help him connect with fans. Kikuchi joked about considering a "muddy yellow," but Hara responded, "I’ve never heard of that color! I’ll proudly carry light green with me."

Sato concluded with, "Let's be together for life as a family!" as they all took a sip of the drink. Only Hara screamed, "Bitter! Why just me!?" Matsushima smiled and said, "Let’s walk along with these colors," and the moment ended with a punchline. Hara protested, "You gave me a refreshing light green, but it's so bitter!" Kikuchi calmly replied, "Sorry, it was a mistake."

Additionally, it was announced that the final audition song, "Rock this Party," will be released digitally on the 28th, marking the group's first digital release. "Hello! We’re timelesz," an album featuring 12 classic songs from the Sexy Zone era, will also be released on the same day.
