Spoiler?
I'm calling it, I don't believe the last of Wolf's words even a little.
It reads to me like some sort of fear of attachment, maybe he lost his old band in some violent manner and never wants to relive that, or maybe they betrayed him and he doesn't want to trust anyone despite his feelings. Or maybe he wants to keep the MC at a distance because that sailor job is just temporary for him (or maybe some means to some other end) and he doesn't want to rope anyone into whatever dangerous lifestyle that he has.
Idk, I find him so interesting. Open up you damned Wolf,
if you are a pirate or something I'll be totally fine with it.
