Gone Again: Special Edition

I'm just fine with the status quo. So what if I'm single.
The happily ever afters that my cousins have found are something I don't need. The company I'm working for is merging with another one, that's what is important. Until I run into my high school sweetheart. Now I don't know what to think.
Seeing him has to be a fluke. Right?
Nope. He's one of my new bosses. That's exactly what I didn't need. He broke my heart all those years ago, and now I'm stuck seeing him Monday through Friday.
The big question is...can I push aside old wounds to keep the work environment from being hostile? Or will I fall into his arms once again?
