Cha Eun-woo, a member of the group ASTRO and an actor, has heightened anticipation for his solo album with a surprise promotional reveal.
On November 4, his agency Fantagio released a video titled ARS Voice #1 on official social media accounts, featuring a mysterious phone number.
The video includes the number 070-8919-0330 alongside the message, “Call me now, before the sound is gone,” sparking curiosity and excitement among fans.
This is believed to be part of the promotional campaign for Cha Eun-woo’s second mini-album, ELSE. Fans responded with comments like, “I feel like I’m wearing rubber shoes waiting for him to come back from the military,” “I’m going to call Cha Eun-woo now,” and “I’m so nervous it’s making my gums hurt.”
Cha Eun-woo’s mini-album ELSE is set to be released on November 21 at 1 PM (KST).
