Oku-sama wa Onee-chan!?

Synopsis

Yukari is your typically sweet "girl next door" type—in my case, both literally and figuratively. Even though she's a few years older than me, we've been good friends since I was a little. But now she's suddenly my wife...?! Apparently, her dad and my neighbor—her dad—set this up a long time ago. So why am I only finding out about it now?!

Before I knew it, we'd moved into a new home where we'll spend the rest of our lives together. Look, I just don't know what to tell you... And for the record, Yukari seems to have been in on the secret, too. Seriously, this was her reaction. She smiled, and said...

"I'm looking forward to my new life with you, honey."

So not only am I suddenly a married man, but my wife is my childhood friend, Yukari. I've got no clue what I'm doing, but I'm kinda excited!

...Actually, though. What now?
