Key mentioned before that he had tried to keep the project a secret at first at Toheart's showcase, but that his members somehow had all found out. This seems to be the occasion that the members find out and nag Key about details.

SHINee bring laughs with their hilarious chatter as they talk among themselves about Key's new unit outside of the group that they weren't given the details on until after articles and teasers went out. When they ask Key to sing a verse from the song, Key sings the line "Sweet Girl~" from 'Delicious', but his fellow members tried to insist that he was copying their own song "Dream Girl". 

But with all the jokes aside, SHINee decided to show their full support by showing up at Toheart's showcase. But Key hilariously commented, "You know the INFINITE members even came to the MV filming" and the SHINee members shouted back, "That's because you didn't even tell us about it!", bringing chuckles from fans.
