[Action]
[Yamamoto is confused. He knows the moment the door opens that something more than usual is off with Mihashi, but being seemingly oblivious is something Yamamoto is quite good at, so he just smiles big and waves.]
Yo~! I found it okay, haha. He's here, right? [It's an obvious question, since he can spot another person within the room beyond Mihashi's shoulders, but he asks anyway. Still smiling, Yamamoto waits to be invited in.]
