That's most probably because they have the smallest age gap. I.N also mentioned in 2kidsroom that Seungmin is the only one who doesn't feel like a hyung to him. So...I guess this is their norm 😂
Yep :v just I.N being Seungmin only younger so Seungmin annoyed him the most :v in some interview when Hyunjin and Felix being asked you wanna be the younger or the Hyung, Felix choose to be the younger but Hyunjin said imagine you are younger than Seungmin and he treat you like I.N, Felix immediately change his decision to the hyung :v
I.n with hyunjin : **hyunjin rubs his face as if he's ready to rip it apart** I.n in mind : such a Nice loving hyung. I.n with seungmin : **sees seungmin's strand of hair on the floor out side his door** GET OUT 🔪🙂💀
Living example that when IN said that Seungmin isn't like hyung to him 😂 I mean, they literally call each other ugly all the time and are teasing/bullying each other 😂😂
Literally, seungmin and i. n are me and my best friend while i.n and hyunjin are me with my maknae POV: Hyunjin and I.
