Jung Hae-in, it's so nice to see your manager is your younger brother! Haha.

When Yoo Jae-suk asked, “It must not be easy to travel with your younger brother,” Jung Hae-in replied, “We both put in a lot of effort. Since he knows exactly how my work goes, he is a great source of support and helps a lot. I think our relationship has now gone beyond family.” It is so nice to see such special trust between them!
