Obviously what she did was wrong, but when she went to the restaurant there was something to video and photograph. If Kamal was grateful for Senthil's investment, he should adhere to the health and safety regulations since people eat there. Also, Kamal seems to have not regret for ditching Janani for that Selvi. Even during the wedding when Selvi was shamelessly going behind Kamal, he did not even say anything. If he didn't want Janani and was ready to blindly listen to his mother then he should have broken up with Janani without raising her hopes. (On another note, why would Saradha want Kamal to marry Selvi? Selvi's mother is the sister of her husband who ran away. After her husband betrayed her like that, why would she want Kamal to marry into that disgusting family)
