Walls: Neil x Iroha
A long time ago, he figured out that it was easier if he didn't care if anyone liked him. If he didn't care if they hated him, if they thought he was rude or obnoxious with skin like a rusty nail (don't touch), then, fine. He could be barbed. He would build a wall so tall and thick that no one could ever reach him, buried deep through on the other side. He made a bear of himself, deep in hibernation, deep into his own winter, and anyone who tried to wake him got snapped.
