[All] Immortal masterpiece, fifteen nights~

At 15ya, I really practiced high notes in college by raising my voice by one octave.

It was a song I sang a lot, lol

BTOB sang this song on Immortal Songs

What the heck, this song is so sophisticated???

ㅋㅋ I guess this stage was already 10 years ago~~ The other members don't seem that different now.

Why is Yuk Seong-jae so baby-like? LOL

BTOB is still a great singer, whether it was 10 years ago or now.
