On the March 29th broadcast of SBS Radio's 'Park So Hyun's Love Game', Eunkwang featured as a guest alongside his 'Three Musketeers' musical co-star Son Ho Young. After singing a cover of "To My Friend", the BTOB member shared, "I like this song a lot. I sang this song with Changsub at a concert. Changsub and I have been together since we did music in high school. "
On the topic of friends, DJ Park So Hyun asked, "I heard that WINNER's Song Min Ho gave you his number on a piece of tissue paper." He responded, "It's true. I gave my phone number to Song Min Ho as well. It's the first time I've ever given my phone number to someone since I was born."
