Cdramas with annoying and sort-of psychotic characters

....yeahh....Ning Meng (crazy one) and He Zhi Juan (pathetic one)

Spoiler alert tho

Ughhh , I cannot fully express my frustration with these characters: Song Ci & Yao Meng Gui. The exact first half of the drama was realllllly good, but on the second half ,it all shattered. The love between Song Ci & Yao Meng Gui completely destroyed the essence of the drama, they are the psychotic couple. Song Ci seems to have a fetish on woman who are hard on him, he takes pleasure on his self-humiliation (Masochist as we say) even though he knew that Xiao Mu pretended to be his sister, he did revealed it to others on any of the episodes, Did he even have conscience? If you'd really watched the drama and understand  well the characters' behavior, you'd surely question the logic of Song Ci and Yao Meng Gui.

You know what, I accept the annoying, disgusting, and psychotic behavior of Yao Meng Gui( a sadist bish) it would satisfy the need for the drama to have a sorta suspense in the plot. The problem all led on the inclusion of Song Ci into the plot, I mean, the writer shouldn't have "rise up" him much into the plot...why tho?? Maybe because the actor had more sponsors for the drama?just so to please the sponsors, the writer tried hard to "insert" Song Ci??? Song Ci and Yao Meng Gui even had a 'sex' scene, like Song Ci isn't even the main lead, How about the main lead(Ji Chen Mo)??? Sorry for the rant tho, I am just filled with frustration on this drama cause this really had a potential.
