I don't know if this book had an editor or a beta reader but 30 pages in and I've already noticed a handful of errors like typos, forgetting to use capital letters at the start of a new sentence and other grammatical mistakes. Usually I can overlook them but these are pretty in-your-face and disrupts the story. This really reads like a Wattpad story and honestly, I've seen better written works on Wattpad.

The author tries to make the MMC "grumpy" but he comes across as a rude asshole. Literally no loving dad in the world would be angry at the person who has helped your daughter out of pretty big trouble a few times. Like heck the FMC brought his kid to the hospital when she fell from a tree and drove her home when she was stranded but the MMC is still "hmph she's young and doesn't have kids of her own so wtf is she doing around my kid". Excuse me, what???

Probably trying to push the grumpyxsunshine narrative, the author tries to write the FMC as this really cheerful woman but honestly, it feels disingenuous. The FMC keeps "bursting into a massive grin/smile" over the smallest things and laughing nonstop at absolutely nothing. 

The characters are also not behaving consistently with their ages, especially the MMC. As a 40 year old man, why are you thinking and acting like a high school boy? The way he argues with the FMC is reminiscent of a teenager in his first relationship. The FMC also retaliates in a very immature manner, mind you, she's 24 not 19. Even after her house burnt down and she's having a mental breakdown, she's somehow still getting into a petty argument with MMC about who doesn't want who. 

I tried to stick this through til the end but unfortunately, it just got too childish and silly.
