GD looks unwilling to call Dara with Noona even though Dara's is 4 years older than him.He called Dara with Noona several times,but it always makes him bumbling(by scratching his nose or ruffling his hair).GD also said that Dara isn't deserved to be called Noona bu him,either because Dara is too cute to be a noona or she's just meant "someone" to him.
