I liked it when Jung Hae-in sang "I Am a Firefly" on Good Day..

I thought of it after a long time, so I watched it again lol

I think Haein is really good at singing, too.

I suppose that’s because he has such a great natural voice.

Just like the video title, the clean, mid-low tone is captivating.

Even just seeing him sing with a big grin is an explosion of excitement.
