It's cute and all, but... erf, they are starting to talk about the elephant in the room (a.k.a tagedy of long life). I don't know how they will play it but I feel sad already.
@DizzyDazzle while he sure lived a looong damn time, like the chapter said, he sure acts like a kid. Which brings the question of what the f he did all this time to know so little about the world.
@lexy It is basically apathy regarding time. He thought his human friend died in a super short time, his sense of time is inherently different and he never felt the need to learn since he had all the time in the world.
Hm, now that they've mentioned lifespans, I wonder if they'll keep the story light and fluffy or if they're actually gonna develop this somehow... Though really, how old is he actually? I'm suddenly getting some Twilight vibes from this hahaha
