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!
