Virtual idol group PLAVE heightened excitement for their comeback by unveiling a pre-release track through a fan-participation mission. The group conducted an interactive event via their official promotion webpage where fans served as 'Secret Agents', collecting 'Star Shards' through mini-games. Once the target score was reached, fans would unlock a reward. The mission began on the 28th at noon and progressed rapidly due to active fan participation, successfully reaching the target score by approximately 5:30 p.m. on the 1st. As the reward, the pre-release track 'Heung Heung Heung (feat. SOLE)' from their fourth mini-album 'Caligo Pt.2' was unveiled. The song features a stylish sound and presents a bright, lovable mood distinct from previously revealed concepts, capturing PLAVE's unique universe and receiving immediate positive response from fans. The audio will be officially released on music streaming platforms at 6 p.m. on the 3rd. Beyond simply revealing content, this event is meaningful as fans directly participated in creating the outcome, further strengthening the organic connection between PLAVE's universe and their fanbase. PLAVE had previously built anticipation for the comeback through sequential releases of various concept photos, and with this pre-release track, the group has fully entered their comeback countdown phase.
