Cha Eun Woo of ASTRO recently shared a touching moment on Instagram after receiving a coffee truck gift from Moon Sua of Billlie. The kind gesture highlighted their close bond, warming the hearts of fans worldwide.
On May 19, Cha Eun Woo posted a photo of the coffee truck sent by Moon Sua to the set of his upcoming Netflix drama The Wonderfuls. The banner on the truck read, “To Eun Woo oppa, from your next little sister after Dongdong, Sua. I’ll always be cheering for you.” The message showed their affectionate relationship.
Additional banners included encouraging words like “Oppa, fighting until the end!” and “Wishing success to the cast and crew of ‘The Wonderfuls.’” The coffee truck was a supportive gesture as Cha Eun Woo films his new series. Fans appreciated Moon Sua’s thoughtful act, especially given her connection to the late Moonbin, Cha Eun Woo’s former ASTRO bandmate and her older brother.

Cha Eun Woo is currently working on The Wonderfuls, a Netflix original series described as a “superpower comedy action adventure” set in 1999. The show follows a group of ordinary people who gain unexpected powers and must protect their city. He plays Lee Woon Jung, a strict and socially awkward civil servant, marking a new role for the actor.
The drama also stars Park Eun Bin, known for Extraordinary Attorney Woo, alongside Kim Hae Sook, Choi Dae Hoon, and Son Hyun Joo. Directed by Yoo In Shik (Extraordinary Attorney Woo, Dr. Romantic), the series is highly anticipated. Production involves NANGMANCREW, Kakao Entertainment, and Cha Eun Woo’s agency, Fantagio.
Fans quickly reacted to Cha Eun Woo’s post, flooding social media with supportive messages. Many praised Moon Sua’s kindness, while others expressed excitement for The Wonderfuls.
“Their bond is so sweet. Moon Sua is such a thoughtful person,” one fan wrote.
“Cha Eun Woo always has the best relationships with his juniors. Can’t wait for The Wonderfuls!” another commented.
This isn’t the first time Eun Woo has received support from fellow celebrities. Earlier this year, BTS’s j-hope engaged with his Instagram post featuring the song “Chicken Noodle Soup,” sparking excitement among fans of both artists.
The Wonderfuls does not yet have a confirmed release date but is expected to premiere on Netflix later in 2025. With a star-studded cast and unique storyline, the series is set to be a major hit.
Cha Eun Woo continues to balance his acting and music careers, recently starring in the 2024 drama Wonderful World alongside Kim Nam Joo. His versatility as an actor and idol keeps him in high demand.
Moon Sua, who debuted with Billlie in 2021, has also been active in music and variety shows. Her sweet gesture towards Cha Eun Woo highlights the supportive relationships in the K-pop industry.
As filming for The Wonderfuls continues, fans eagerly await more updates. The coffee truck event has only increased excitement for both Cha Eun Woo’s new project and his heartwarming friendship with Moon Sua.
