SM Entertainment's hitmaker Yoo Young Jin (38) praised BoA and TVXQ in an interview with Yonhap News and said that the former has surpassed his expectations and how hard-working TVXQ is.
"BoA's special ever since I gave her her debut song 'ID:Peace B.' I made that song and although I let her listen to the demo track, I hadn't arranged how it was going to be interpreted. We recorded the song 3 days later and the result was beyond what I had envisioned. BoA's ability to interpret a song is excellent. BoA is still evolving," Yoo Young Jin said.
"TVXQ's been flying back and forth between Korea and Japan and in a year, they get to rest for only a week. The group's vocal abilities have improved quickly considering how tired the members are," Yoo Young Jin evaluated.
He also shared during the interview that he occasionally teaches TVXQ members on writing songs and advises them that writing songs is not about wanting it to be the title song of an album.
