In the year 2055, Dr Pratham received an award for discovering a new coronavirus. As he goes down memory lane, he remembers the summer of 2020. Back then, he was a naughty six year old boy, called "Bholu' affectionately by his family. An illness called Covid-19 was spreading all over the world. Everyone had been forced to stay inside their homes during the lockdown. All of a sudden, Bholu's happy and carefree life was turned upside down. Instead of normal, physical school, he had to learn to adjust to attending online classes. He also had to learn to play all by himself as he could not meet his friends. Staying away from his school and his friends, Bholu became miserable and lonely. Then one night, in his garden, he met Kovi, a baby coronavirus. From that moment, an unexpected friendship began. Playing together and talking about the pandemic and science, they found an enchanted purpose. Finally, Kovi made Bholu promise something and that transformed Bholu's life forever.
