Vocalist K.Will (Kim Hyung-soo) shared a fun and candid music talk with singers Kim Bum-soo, Lyn, and Heize.

K.Will's agency, Starship Entertainment, recently released a new episode of his YouTube channel, 'Know Your K.Will,' featuring the trio.

In the video, K.Will met with Kim Bum-soo, Lyn, and Heize, whom he encountered in Manila for the 'KOSTCON (KOREAN OST CONCERT)' held in August. They gathered to share various stories.

Heize recalled her first meeting with K.Will, saying, "Before I appeared on 'Unpretty Rapstar 2,' I met him at a studio while working on music alone. I greeted him, and he stopped, kindly returned the greeting, and left. That memory gave me great strength." Lyn agreed, stating, "Hyung-soo takes good care of people; he gives 20 for every 10 you give him." K.Will blushed slightly but smiled proudly.

A serious discussion about music also took place. When Lyn confessed, "I tend to be overly emotional when I sing. It's polarizing. If someone thinks, 'Listening to this makes me tired,' they'll skip it," K.Will responded, "It makes me think a lot. I wonder if my songs have made anyone tired," drawing laughter with his self-reflection. Kim Bum-soo humorously added, "I apologize. Were you all very tired?"

The four artists who participated in 'KOSTCON' also shared their concert experiences. Kim Bum-soo expressed his awe at the audience's reaction, "They weren't just singing along to my songs. It was a deeply moving experience I haven't felt in a long time." K.Will agreed, sharing, "After coming backstage, I said, 'I feel like a star again.'"

At the end of the video, when asked about an 'OST they want to steal,' K.Will mentioned Lyn's song, referring to his remake of 'Back to the Time' from the webtoon 'Moon in the Day.' He explained, "It was a webtoon OST, not a drama OST. Fans said the song fit the narrative well and attached 'Back to the Time' to it. Even though I lowered the original key, there were reactions saying my voice was audible, which is how it came to me." He also added, "It was the first time one of the songs I sang hit number one on the karaoke charts," prompting Lyn to jokingly reply, "That must have made me a bit jealous," bringing more laughter.

Meanwhile, K.Will continues to entertain viewers every Wednesday at 5:30 PM KST on his YouTube channel 'Know Your K.Will.'

Netizens reacted positively to the latest episode of 'Know Your K.Will,' praising the chemistry between K.Will, Kim Bum-soo, Lyn, and Heize. Comments included sentiments like "It feels like watching a gathering of close friends," "K.Will's kindness is no joke," and "The OST stories were so interesting, I learned a lot." Many expressed anticipation for future collaborations and behind-the-scenes stories from the artists.
