The only reason Jaejung isn't jealous of Jun Su (Xia) who lives in a high-rise apartment?

Singer Kim Jaejung says he is not at all jealous of Kim Jun Su (Xia), who lives in a 4.8 billion won (about $5.5 million) high-rise apartment.
On the 14th, Jaejung appeared as a guest on KBS Cool FM's "Park Myung Soo's Radio Show" and said, "Before, I couldn't get along with people.
"I used to enjoy going out, but recently I've started to like being at home," and "I keep my house clean." Park Myung Soo asked, "Are you decorating it nicely like Jun Su (Xia)?"
He talked about Kim Jun Su (Xia), who worked with him in TVXQ and JYJ. Jaejung responded, "I don't live in a high place like Jun Su (Xia)." He added, "I live on the bottom floor.
Jaejung said, "I went to that house too, but the problem is that the windows don't open. No. The windows have to open wide," he said, making everyone laugh.
Of course, JAEJUNG already lives in a very nice house. JAEJUNG's house was revealed for the first time on KBS2's "Convenience Store Restaurant" broadcast on the 24th of last month.
The unique room structure, gorgeous lighting, and even the interior and accessories were reminiscent of a gallery.
