I have to say personally when i started this show i wasnt that interested . I didnt know either of the main actors but it was on netflix and i saw so many other great reviews . What really made me watch this was the super cute merch on aliexpress . I sluged through the first 15 episodes which for me felt most like backstory but then it turned out amazing !! Each episode is definitely necessary, if you find yourself getting bored then please keep going ! Its definitely worth the watch !! I grew to love both sean and yibo and i now try to watch everything they are in ! Fantastic job !!
