Okay, first of all 당신 should know I'm really bad at describing people & stuff, so don't say I didn't warn 당신 if this turns out to be a disaster. ;P But for Nic, I really wanted to give this a shot, so here it goes ;D
# 1: his amiability
Nic is probably the most amicable person 당신 will ever find (it's an existing word people! Look it up ;P) I've said if before, and I'll say it again: I will never understand people who do not want to be 프렌즈 with Nic, let alone hate them. And if I do ever encounter one of those people, they will get slapped! I'm not kidding.
