I believe I've seen another manga that adapt this exact Vocaloid song years ago mmm...
Edit: apparently after all this years, it's originally from a famous Japanese Yahoo! Answer, became a huge meme and made into song with Vocaloid mmm...
NO! Why oh why is my wife dead?! I was planning on having wild sex with her when I got home! Wait a minute! She's still warm. I can get in a quickie before she gets cold.
NGL if this was a common occurrence I'd probably get a divorce. The fact my wife could actually be dead and I would first think it would be a joke would be a rollercoaster of emotions that would 100x worse than just assuming dead.
