It goes something like this: for the most part, I was pretty stoked about the whole book. Then came The Point of More Complication - Peripeteia? - that moment where stuff "have" to go to... bad, in order to go right.
And that was not handled exactly to my satisfaction, but I was mostly able to get over that.
As for some characterization, this is a romance book. Like, every romance has this ratio of pure romance and then those Other pursuits, which can range from paranormal or action scenes to simply being dedicated to your work or resolving family or friend relationships and this one had a demisexual, shy, neurotic genius with exactly one friend, who now has a new assistant and... well, it did not take that long to get all personal, thought maybe longer than most books take and that was nice, because it was true to the characters. You have a nasty ex who is there for... dunno, actually, maybe just the token Shi...y ex, from whom our MC has to recover, yadda, yadda. If you made him a virgin, you did not have to add the ex, not when he's going to be just this empty parody , just a representation instead of a real person.
Anyway, the romance, told with 2 POVs, was pretty sweet and a bit kinky but mostly as a "I am fidgeting and nervous mess and letting go off control a.k.a letting some tell me what to do in bed is centering and anchoring me and quieting the voices in my head".
Recommend.
