What made akshara and Naksh sob so profusly?

Akshara had to face a trouble in the absence of Naitik lately.
While Naitik is away these days to Surat for business work, his son Naksh just can't bear to have his father live away from him.
Lately, Naksh took a daring step by deciding to visit his father in Surat, all alone!
After finishing his school, Naksh got his hands on a train ticket to Surat from his bestie Yash. He went all the way to the railway station to catch the train to the Diamond city.
However, he neither informed Akshara nor mentioned a word about it to any member of his family.
Poor Akshara got worked up and worried about Naksh when he failed to reach home after school. She took her car in search of her son like a crazy all over the city.
At last, she heaved a sigh of relief when she found Naksh at the railway station. She hugged her child lovingly and burst into tears.
This event brought relief even for Naitik, who was worried for Naksh all along.
