Oh, that sounds fun! Asgore's kinda in a similar boat - he's actually quite good at socializing like a normal person once he's there, but he's got some weird hang-ups about people not actually really wanting to associate with him so he's not great at initiating unless it's with someone he already knows fairly well. Even then it's a bit of a crapshoot.

Fun fact: one of the first people who met him when he arrived here was Mickey Mouse, who proceeded to threaten him to stay away from everybody because Chara had told him about Asgore having killed human children! So that was hilarious in concept but super did not help, he didn't talk to anybody for like a month.
