In a recent 'UV Room' episode, AKMU's Chanhyuk wasn't happy about a new proposal.
On May 31st, the YouTube channel 'UV Room,' run by comedian Yoo Se Yoon and singer Muzie, released a video called '[UV Recording Studio] AKMU vs. Devil Musician.'
The video featured AKMU siblings Chanhyuk and Suhyun. Fans were surprised to see Chanhyuk in the studio, as it was believed Suhyun would be working solo with UV.
UV members asked Chanhyuk, "Did you just stop by since we’re recording with Suhyun today?" and then asked Suhyun, "Are you preparing solo too?" Suhyun, caught off guard, asked Chanhyuk, "How did you get here? Did the manager tell you?"
Chanhyuk made his feelings clear, saying, "It's not like you’re 'stealing' Suhyun, but she usually works only with me, and I wasn’t informed about this."
He then asked, "Shall we listen to it? What is it?" Yoo Se Yoon explained, "It's a sexy concept that Suhyun hasn’t tried before."
Chanhyuk, clearly unhappy, said, "I knew it. Sexy concept for my sister? No way. She’s still in her 20s." When Muzie's guide track played, Chanhyuk added, "Sorry, I really don't want to say this, but it's tacky," making everyone laugh.
