So on this episode of [Eng subbed] Teen Top (틴탑) and 100%'s Rising Brothers Ep. 7 (5:49) they had to roll a dice and whatever number they got, they had to take off a sticker on the game board that revealed a letter. With that letter,  they had to think of a food or drink that started with that letter. It was best to think of something somewhat small and easy to find.

Niel suggested milk. Milk was something easy to find, and it could be served in a small bottle.

He was sent to go get milk from a nearby convenience store, and he asked the cashier where he could find milk. They guy shouted, "HEY GET THIS BOY A BIG CARTON OF MILK!!!"

Niel knew that wasn't what he wanted, at all, but all he could do was smile and stutter. Then, when you see the man handing him a big ol' liter of milk, Niel is whispering, "Ah-an..." He can't even get out the whole aniyo because he's too polite to correct it.

WHISPERING? COME ON NIEL... HE CAN'T HEAR YOU.... Speak up please... Why are you so cute? xD

Then when he gets back, he gets scolded by everyone because the milk he bought was too big. Mind you, they need to finish it completely before they can move on. So understandably, they were upset at him. 

All because he couldn't say no xD

Lol. Hes just so kawaii~~
