It's a good kinda alternative to pair with that mamasuki one, where the guy in that one is a champion and the story is a bit more serious in tone, whereas this guy is a total fuck up in a much lighter non-story.
I always find it weird in anime/manga how an adult woman, who's already a mother, meaning she has already kissed plenty, and has plenty of sexual experience, gets extremely flustered like a middle/highschool girl
