This HaBO is from Jam on the Brain, who is looking for a Mills & Boon title:
The book I’m thinking about is a Mills and Boon (Harlequin).
The heroine works for the hero. The heroine has a male best friend who has a girlfriend that thinks these besties since childhood are having an affair (or that at least it’s unrequited on heroine’s part). Boss finds out and says let’s tell everyone we’re dating (). There’s a scene in which male bestie barges in on a weekend to do laundry and I remember something about quince or damson jam. Climax scene is in an elevator in the office I think.
I’ve looked everywhere and can’t seem to find the right one.
Help me HABO friends, you’re my only hope.
Would love to know how jam is involved!
