It doesn't have to be someone you're close with either. There are many users here that I just find cool and like.
I'm sure there are even more but right now I only can think of these ones:
Armedryu - The nicest Once on this planet.
Ves - one of the nicest and a very cool moderator. I'm not close with you but I really like you.
Kairina - you love Suzy, Aespa and Jennie. You are the greatest.
Pikachu-Senpai - You are such a sweetheart.
SandyBee3 - You always say what I think. You are so sweet.
kittykitka - the best blink in the world. Couldn't name someone who is nicer than you.
monalisalove - Greatest Lisa supporter.
BRIYANI - sadly not close but I really love your comments. BTS can be proud to have you as Army.
selfmate - Coolest person on this planet.
atropos - Our Blink taglist Queen. Nice and sweet.
Twicegraphy - Coolest Once here.
@ripia - My drug dealer. You know I'm addicted to allkill badges and you don't make it any better.

red-silk - Cutie and my favorite maknae.
