A: iKON and Winner are far too senior to be put on this list

-I think it would be better to refer them as the youngest group in each companies..

-The OP is really prepared..ㅋㅋㅋ Look at how they already answer the comments that people would leave on this post..ㅋㅋㅋ

-NCT and iKON's debut date are only 6 months apart..ㅋㅋㅋ

-JYP should've released better pictures for those boys..

-Well, SM keeps on adding new faces to NCT that's why they still feel like rookies for us..

-Why does NCT have a lot of members..ㅋㅋㅋ

-Well, SM really does have the best visuals.. No doubt..

-I have a feeling that SM won't debut any other boy groups and instead, they would just keep adding new members to NCT.. Don't you think so?

-Well, SM is going to add new members to NCT so.. I guess it's fair to call them a rookie..

-NCT's members are so handsome.. I'm crying..

-Didn't NCT just add some new members to their group earlier this year?

-Whoa, it's Bang Yedam..ㅋㅋ

-I'm looking forward to Bighit's upcoming boy group..
