Yeah sometimes that happens. Like the publisher says to the mangaka "You gotta wrap this up in 2 chapters". But sometimes exhausted mangaka wrap things up prematurely because they are so burnt out. I wonder what the story was. So many things set up for a resolution that are never addressed again.
exactly my thoughts as well (if you're talking about rokuomi's friends, forgot their name already). It's like they're telling Rokuomi to take care of their daughters if they die.
Grandpa is naughty!
