After watching half of the drama I realised why this drama has this low rating, because initially I thought it is interesting. Why I felt it is cliché is, the whole secrecy in the drama is about mystery of the FL’s sisters suicide. Initially it is portrayed that she was cheated or betrayed by second ML “he proposed her and forced her to have sex and after that he told to ML that she made the move to have sex”, for this reason it is understandable few weak minded people will commit suicide, but in the last second or third episode it is shown she had deep crush on ML and wanted to keep close with him even though they may not from the same world. This is the only thing I didn’t understand if she had that much serious feeling for ML than why did she accept the second ML confession and kissed him and slept with him in the first place. After slept with the second ML she feel embarrassed to face ML that’s why she decided to commit suicide. This is totally cliché.
