i dont think anant acts foolish. he is also in love as much as navya is. but anant is a confident guy and he tries to get what he wants while navya is always confused. and he is doing all these things because he is also in love with navya..that too for the first time! its a new feeling for both of them.
i dont blame any of them for their acts. that's how a teenager in love for the first time would act!!!
