i have a question

i started to watch the serial arasi just a week ago but i read ur updates reguarly

i have a question who is the kaveri i didnt see her yet in the serial what role she is playing in it?

Well Kaveri was the biggest headache but not now in the serial as everyone hates her but now everyone loves her 😃 .

Kaveri is the daugther of Selvi the daugther of Arasi. Kaveri was brain washed by her twitched father GJ so she would always like a GJ all the time. But had hatred over Selvi 😕 but Selvi knows how to handle the bads to annoying by just beating them up and giving scolding. Selvi sended Kaveri to a private place to grow up by not seeing Gj. When she returned back after couple of years back but since this is a serial she come back older and annoying 😡 😡 😡 . Sine Selvi blood contained Arasi; Kaveri would imiatate Arasi all the time and get into fights with her. But Kaveri is a nice girl once she found her father true side and doesn't accept him as her father 😃.

We have not seen Kaveri for a few episodes now, so I understand your confusion. Azhagiya_Barath has answered your question, but I would like to add a few more details:

At the moment they are concentrating on GJ's other daughter Aishwarya, and GJ's son Sachin. Both of them are GJ's children with Thamarai, Selvi's dead best friend. Therefore this makes Kaveri half-sister to Aish and Sach. At the beginning, Kaveri used to trust their father completely, while Sach and Aish did not. Now Aish is the one who believes GJ's lies while Sachin still doesn't. The last we saw Kaveri had learned not to trust her father but since then GJ had "saved" Aish in Malaysia and we don't know what Kaveri's reaction is.

is kaveri become big or the same girl is acting
will she come in the serial again

Kaveri is played by Nivetha aka the same girl who played Gawri in My dear Bootham and yes, she will act in Arase, as for now, her track is not important, but keep an eye..she may appear 😊
