Shin Seung Hoon took to his personal Instagram account to praise idol Kim Jae Hwan!

On the April 27 episode of 'Immortal Song,' the former Wanna One member performed a stellar cover of Shin Seung Hoon's hit song "I Believe," bringing out his acoustic guitar to add a bit of his own personal style to the stage. The rendition received so much praise that Kim Jae Hwan ended up winning the episode.

"I've seen a lot of hoobae singers perform my song 'I Believe,' but Kim Jae Hwan! The way that he interpreted the song in his own way with his guitar was fantastic! It seems he will become successful as a solo artist as well," the ballad singer wrote, attaching his praise to a video of Kim Jae Hwan's performance.

Meanwhile, Kim Jae Hwan is currently preparing for his solo debut through agency Stone Entertainment.
