Překlad - Brazilská portugalština-Japonsky - Feliz Aniversário!! Te amo!!

こんにちは Cisa。ここでは相手が"tu"なので、「ございます」はていねいすぎると思います。「おめでとう」だけで大丈夫ですよ。

Hi Cisa,
Yup, cesur is right when she says you don't need the "gozaimasu" because you're talking to a "te" (familiar) person.
(And actually, you wrote "gazaimasu" anyway)
So I'll cut the "gazaimasu" and approve it now.
