People say there are many ballad singers with more hits than Sung Si-kyung

‌But in reality, there are only about 4 people who are clearly mentioned as having more.
Lee Moon-sae / Shin Seung-hun / Im Chang-jung / Lee Seung-chul
It's hard to say that Byeon Jin-seob, Jo Sung-mo, or Lee Seung-hwan are definitely ahead of him.
Even if you include them, it's only about 5 or 6 people in total.
Some even mention Yoon Jong-shin and Kim Bum-soo, but that just sounds like nonsense to me. lol
