NCT's Mark, who most recently released his 1st solo album 'The Firstfruit', appeared as a guest on Na Young Suk PD's new YouTube talk segment, 'Bubble Bubble'. 

On this episode, fellow artist Lee Young Ji joined Mark for at-home Haidilao with host Na Young Suk PD. 

While talking about Mark's positive attitude at work, Na Young Suk PD asked, "When was the last time you got angry?"

After some thought, Mark said, "When one of the members takes out a cup to use, leaves it on the table, forgets that they already took out a cup, and goes and gets another cup and doesn't clean up the dirty cup..."

Hearing this, Lee Young Ji remarked, "Wow this is pretty detailed," while Mark added on, "But I don't say anything to that member. I just clean it up myself."

However, idol also declared, "Even though I don't say anything directly, in my head, I tell myself, 'I can't marry that member'."

Na Young Suk PD deeply(?) empathized with Mark on the matter, commenting, "I'm the same way. I never confront the person, but in my heart, I label that person with a little tag. This person is 'the one who probably can't get married'." 

To this, Lee Young Ji asked, "If that person loses points that way in your heart, then can they ever redeem themselves?"

Mark answered right away, "They can definitely redeem themselves. My standards aren't that high. Even if they clean up the cup once, I'll be like, 'Oh hey, you cleaned up this time. Good job'."
