Abrupt ending, but I can imagine Wakame was running out of ideas and had already committed them to a relationship, too. I'm hoping for some extras wrapping up the romances of the other couples, but I'm glad they didn't drag this out way past its prime, at least. Still hoping for a doujin or something one day exploring the main couple as full adults, though!
I'm at least so glad it's forever set in stone that they stay together, though! Nice shot with the granny-hands. Rest In Boobs!
