Netizens are talking about Johnny and Mark's keeping their 'promise.'

On social media outlets, posts revealed that the two members from NCT are still spotted using their respective passport wallets handcrafted and gifted to each other four years ago. As part of the official YouTube content, Johnny and Mark each made beautiful passport covers back in 2019. 

Just a few days ago, the two idols displayed their red-colored passport cases at the airport, proving that they are still actively using the items.

In the original video, the boys are seen remarking that they will "use the passport forever," especially as Mark says: "I wish Johnny-hyung would really use it forever."

Although Johnny, in that moment, joked that that's "not gonna happen," he was also seen using the one made by Mark at the airport.

Netizens commented that it was "so cute to see that happen" and that they can "bet they will keep those items forever in their lives."
