4 stars - for bringing out the real struggles for a start-up company and the ups and downs they have to face. If anyone is really thinking of a tech-startup, they can definitely take inspiration from this series leaving aside the emotional scenes, the love angle and revenge part from it.
2 stars - for the story around the pen-pal. The chemistry shown between each narrowly ended just being a love-story for no good reason but his big hands. Didn't make sense at all. Finding comfort in a person after waiting for 15 years to meet the one and not able to define the real reasons for falling in love.
