Well, with the much needed motivation, I've decided to write a bunch of different boyfriend scenarios. These will also have AU versions of some characters, so each set of ideas will have two chapters. I'm not quite explaining this well, but it's a-okay for now. If you have an idea I would love to hear it, mercy knows I'll need some help with these after a while. I own no characters in these stories, nor do I own the art. Undertale is owned by Toby, and any AU ideas belong to their respective creators. I own only the plot(s). Thank you.

This is the second story to "Unexpected Love" so if you haven't read the first book you should probably read that first so you aren't confused. But anyways, enjoy! You wake up on the cold floor in the old lab that Alphys had found. You felt strange and the only life form that you could find in the Underground was Chara, who had somehow gotten out of your consciousness and now looked like a normal human. You find out that six months had passed and a child named Frisk had freed everyone and the barrier was broken. Now, with Chara somehow befriended, you leave the Underground in search for your monster friends. And most importantly... Sans. Author's Note: enjoy my awful writing! ((COVER ART IS NOT MINE))
