The Hate Project by Kris Ripper
This arrangement is either exactly what they need--or a total disaster
Oscar is a grouch.
That's a well-established fact among his tight-knit friend group, and they love him anyway.
Jack is an ass.
Jack, who's always ready with a sly insult, who can't have a conversation without arguing, and who Oscar may or may not have hooked up with on a strict no-commitment, one-time-only basis. Even if it was extremely hot.
Together, they're a bickering, combative mess.
When Oscar is fired (answering phones is not for the anxiety-ridden), he somehow ends up working for Jack. Maybe while cleaning out Jack's grandmother's house they can stop fighting long enough to turn a one-night stand into a frenemies-with-benefits situation.
The house is an archaeological dig of love and dysfunction, and while Oscar thought he was prepared, he wasn't. It's impossible to delve so deeply into someone's past without coming to understand them at least a little, but Oscar has boundaries for a reason--even if sometimes Jack makes him want to break them all down.
After all, hating Jack is less of a risk than loving him...
