Yay! More extras. Thank you for the TL 😁.
It's always been sad when you stop growing. More so if you stop growing at a young age. Though with that last joke was the author trying to make a joke and just pushed it too far or the translation off or do they just not know US movie ratings? Because there is no PG-12, just PG-13 which seemed to me like the setup of the joke since she just turned 13. Like "hey I can finally go watch PG-13 movies without an adult; oh no everyone still sees me as a toddler because I'm short."
Also Doraemon but company slave in an office setting is dark. Everything is just creepier with an adult.
