Alternatively, could it be a mistranslation or a transliteration issue? For example, "Amma" is sometimes used in Indian movies as a name. Maybe it's a reference to a specific movie or book? I should consider possible variations. "Kambi Kadhaai" might be a known Indian film, like "Ponniyin Selvan" or "Karnan," which are historical epics in Tamil cinema. Wait, "Kambi Kadhaai" is actually a Tamil historical drama series from the early 2000s, right? Created by K. Balachander. That might be what the user is referring to, but they added "Amma" at the beginning. Maybe they're conflating titles or it's a mashup of different works.
