GMMTV probably never came this close to doing justice to SOTUS before this one. It's a well done "engineering-senior&junior" in middle of dozens of other tries at the SOTUS legacy

Japanese romance with the same light vibe to the narrative, somehow. Both treat their characters with fariness and develop them in a similar way. Also, they're both the type of series that gives comfort to people who watch them, because the plot is fairly uncomplicated and more realistic in a matter of actions-feelings.
Kieta Hatsukoi is more juvenile, but it gives me the same vibe as Perfect Propose.
