Seems he's got that same calming skill Ainz from Overlord has wouldn't really call him angsty, seems like a pretty normal reaction to suddenly be dragged into another world away from those you hold dear and being put in life threatening situations and just barely being able to get by financially. Honestly when I put it like that it wouldn't be that weird for him to be more frustrated, yeah his conditions aren't as bad as Death Mage's but in that one the MC ends up a pretty broken individual completely disassociating himself from his past self, this seems about apt for his circumstances.
