GRAY recently released "Moon Blue" with Dingo Music and started a Moon Blue Challenge. He nominated Korean UFC fighter Korean Zombie as well as Kang Daniel with the caption, "Nielie @daniel.k.here do it if you have time 😝 😝 😝"

Kang Daniel stepped up to the challenge and posted his cover on Instagram and TikTok:

Gray*-hyungnim's new song #moonblue #moonbluechallenge please give it lots and lots of listens  🙌 🌕

*He used the word for the color gray

GRAY replied under Kang Daniel's Instagram:

Haa 💙💙💙 I love you. I'm touched for real... ✨✨✨

He also reposted the challenge on his SNS with:

Nielie is love 💙

Amazing ✨ @daniel.k.here Our Nielie love you 💙

to which Daniel replied with:

🙏 🙏 The song is great so of course hehe

The challenge and their cute exchange quickly became a hot topic. Netizens reacted:

Isn't his physique crazy ㅠ 

Ah I really like Kang Daniel's dancing, he makes it look so comfortable and free

His arms are so long

Waa it's crazy his dance line is so pretty ㅠㅜㅜ

At 0:26 I love the part with his shoulders ㅠ

Kang Daniel is so cool, even with little body movement he gets right feeling and his arms and legs make perfect angles, I'm so jealous of his dancing

Normal clothes f**k he's just wearing a white tee and jeans but he looks great and he dances so well

His dance line is clean and looks great

"Gray-hyungnim" how cute

He dances well, the groove is nice and the dance is not excessive so it looks neat and pretty

Kang Daniel's control of his strength is crazy

I don't know how to explain but the dance looks so good because he doesn't overdo it

I hope they have a collab ㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠ

His dance line is pretty with his wide shoulders and long arms, I'm jealous of his groove

I'm going crazy and can't stop watching

The dance and the song are addicting

GRAY uploaded a bunch of captures ㅋㅋㅋㅋㅋ Moon Blue is a good song and Kang Daniel dances well ㅋㅋㅋ Their grooves match each other ㅋㅋ

Crazy... his physique and dancing I'm going crazy ...
