I really wanted to learn this Gwiyomi game which BTOB's Ilhoon has done a lot of times before.

Its really easy but the lyrics is not haha. 

I had to replay the video about 6 times in order to get it.

"il deohagi ileun gwiyomi.
i deohagi ineun gwiyomi.
sam deohagi sameun gwiyomi.
sa deohagi saneun gwiyomi.
o deohagi oneun gwiyomi.
yuk deohagi yugeun gwiyomi.
chil deohagi chileun gwiyomi.
pal deohagi paleun gwiyomi."
