On the September 23rd episode of 'Magic Eye', Noh Min Woo revealed the reason behind giving his wallet to his date after an expensive outing.

Host Hong Jin Kyung said, "I went to a restaurant with someone I knew to eat together. At the time, [the restaurant] had run out of the champagne I [usually] drank.  I asked the employee for a recommendation and drank that champagne, but one bottle was as much as 300,000 KRW (~ $290 USD). We did not even drink one bottle but three to four. From then on, I always ask for the menu rather than a recommendation."

Noh Min Woo then said, "If it is a situation in which there is no choice but to drink expensive wine, I accept the expensive wine that was recommended with no price written down and drink it even if it is expensive. And then, when it is time to pay, I give my wallet to my girlfriend, and after telling her to pay the bill, I go to the bathroom."

He explained his reasoning, saying, "If I give my wallet to my date and trust her with it, she thinks we're on close enough terms for me to give her my wallet. Secondly, she would see the price. If she is someone who thinks it is not great drinking something so expensive and doesn't want to do so, then in future dates, she will mention it first."

Wooyoung brought up the possibility that by the time Noh Min Woo comes out of the bathroom, both the girl and the wallet could be gone, making everyone laugh.
