Astro's Cha Eun-woo made his first official appearance in nine days.

On April 29, Cha Eun-woo attended the KonnecThai event held in Thailand.

He had canceled his scheduled activities and returned to Korea on April 20 due to a sudden piece of news, but he resumed his schedule after nine days.

Cha Eun-woo appeared at the KonnecThai event, walking the red carpet and posing on the photowall.

On April 23 (Korea time), Prestige Entertainment announced through their official SNS, "Artist Cha Eun-woo will participate as planned in the KonnecThai event, a cultural exchange event between Korea and Thailand, with main artists from both countries, VIPs, guests, and many fans."

They added, "This decision was made after a deep discussion between Fantagio, Cha Eun-woo, and the organizers."

On April 19, Astro's Moonbin suddenly passed away. Born in 1997, Cha Eun-woo and the younger Moon-bin, born in 1998, were the only close friends in the group.

Cha Eun-woo, who was in the United States for a schedule at the time, quickly returned to Korea to visit Moonbin's funeral.

He also left a letter at the memorial space for the late Moonbin at Fantagio's office.

In the letter, he wrote, "Bin, I miss you on this night, you bad guy. Be hundreds of times happier on the moon. I'll take responsibility for what you left behind, so don't worry too much. You've worked hard. I love you and I'm sorry, my friend," adding to the sadness.

Many people, including Cha Eun-woo, who remember the warm and bright side of the late Moonbin, are going through a sad time. However, they are also making efforts to return to normal life for him.

Fans continue to offer comfort and support to Cha Eun-woo.
