The 3rd person singular for "to have" is "has" and you only need to add an "s" to words if they're plural. I strongly recommend a quality checker and a different proofreader to catch the typos and poor grammar, especially if you're not native. The mistakes are frequent and consistent. For a comedy series based a lot on word play and situational comedy through specific phrasing, this also reads too stiff and unnatural and the readers needs to be able to infer what is wrong on purpose and what isn't.
There's also an asterisk on page 33 with no TL note added anywhere. And a typo in the credits page.
