The girl has a glowing personality to play off of the boy's aloof character and they find themselves partaking in saucy scenarios. It's very much like what you get in every standard rom-com like it.
Only thing that's unrealistic is that she isn't making her fanbase pay to see her titties, but it's her natural perverted desire for voyeurism & attention that'll make her best girl when this get's an anime in a few years or so.
