[This guy's briefly left the house to gather some supplies (he has to eat sometimes, he guesses, when he's not busy with Projects Other People Wouldn't Understand), but it seems the Usyagi have taken advantage of his absence to seal the house shut.
Rather than the usual rent notice, in his case he's got a list of activities he could do in order to properly bond with other residents! Go grab a coffee, buy some cake, visit the other islands, head to the park (something always happens by the Park)... Of course, he's doing the reasonable thing, and embracing this new task, setting out to mingle with the other people in the world.
Or rather, he's stubbornly staying outside the door and trying to kick it down. Loudly.]
