I thought the end of the Drama itself was nearly perfect, and would actually have scored it even higher if the final scene had been with the child actor, not the adult. Less is more. Which is why I loved this BTS because it added nothing to Drama, but gave a genuine glimpse of the 3 lead ACTORS, right down to Ko Chia Yen's censored reaction to having to call Greg Hsu “Zi Wei gege”. Great stuff, and a fitting treat for the viewers that didn't come across like "here's how we would have liked to end it". Am amuse bouche for afters
