Gil has been writing sad songs since his break up

The May 7th episode of MBC's "Infinity Challenge" continued from last week's 'dinner show special' with the castmates picking teams for an upcoming gayo festival. While members stood in front of singer Lee Juk to be picked as a partner, Gil asked, "Do you have a good relationship with your wife?" Ignoring the stares of confusion, Gil continued, "This is important for music." When Lee Juk replied by saying that he has a good relationship with his wife, Gil sadly gave up trying to become partners with him and stated, "That's not enough for my music." Upon hearing this, member HaHa stated, "This hyung has been writing a lot of songs lately!". Gil hinted at his breakup with Park Jung Ah by emphasizing, "Musicians should be sad." Lee Juk then asked, "Didn't you sing about farewells ('The Girl Who Can't Break Up, The Boy Who Can't Leave") even when you were happy?" HaHa quickly joked, "Their (relationship) wasn't good back then" making everyone in the studio burst out into laughter.
