The camaraderie between YG Entertainment's big senior group, Jinusean, and maknae group, iKON, is super cute!  

As Jinusean made their long-awaited return with "Tell Me One More Time" recently while iKON are still preparing for their debut this year, it's pretty heartwarming to see the latter take some time to congratulate the former on starting off this year's YG promotions.

Jinusean's Sean updated his Instagram the other day with, "Support message from YG's maknaes.  What night is tonight?  Jinusean night!" and posted a short video in which iKON's leader B.I states, "Hello.  This is iKON.  We congratulate Jinusean on their comeback and will diligently support you."

The other members raise their voices, as well, yelling, "What night is tonight?  Jinusean night!"  Kim Jin Hwan adds, "Jinusean, fighting!"

Too cute!
