The drama focuses on 2 main characters. In the end, the female lead chooses the other character which has not been introduced to the audience for entire series. Whoever came up with this story should be bestowed with THE WORST STORY OF THE YEAR award.
I would like to thank the makers to keep the episode lengths to 27 mins. It reduced wastage of my time. Skill of story writting seems to be in a grave danger here. Drama doesn't takes you to intricacies of human connections but delves into what we can say as buyer's remorse.
