I can understand why this much fan following for this drama after watching this. Its mainly because of Main leads chemistry. They both are just awesome just lived throgh the characters.Its very natural beacuse of flawed main lead characters. Its reallly enjoyable to watch types Hate/Selfishness become love&care.this drama OST is a very catchy melody that will become ur favorite at the instant you hear it. This drama has all basic aspects of chemistry, love- hate relationship, friendship, funny, Most romantic moments. If you thinking about watching then pls go for it.U wont regret it.

I felt few aspects was wrong in this drama like leaving negative character without any punishment/justifying his actions, tharn groping type without his consent at begining, tum & tar relationship ,Tar looking very young to be in relationship with tharn etc.But after reading novel i felt the characters are correct in their viewpoints.obviously its difficult to convey every charcters inner thinking/struggles is difficult to show through drama.But the best part to compare novel and drama is how the 2 actors give life to those 2 beautiful charcters(THARN&tYPE) in screen.Kudos.

Even throgh i felt the above points are logic misses, I really enjoyed the drama and eager to watch part 2.

U should watch it once for the chemistry itself.
