Best CDrama unforgettable masterpiece

This is list per my criteria. I watched over 30 C Dramas, I opened (watched first 3 episodes then stopped) over 60 dramas. I skip the drama witch doesn't meet the following criteria

FL & ML have good character development

• not to dark, there is humour in their character 
• not to stoic and aloof
• smart - while most ML are smart, for european viewer some FL might be to infantile which makes it unwatchable. 

Plot

• Very important criteria is that ML and FL don't fall for stupid tricks of their rivals and love rivals.  
• No repetitive c drama content. most of C drama plots are about palace intrigue, rebirth, reincarnation, time travel and that part is expected to be repetitive since they have quota to produce each year. But scenes are also repetitive, ML and FL getting heavily injured then the other spoon feeding them to health, this scene is unbearably repetitive in almost every c drama.  And many other scenes you will soon start fast forwarding. 

Wuxia, Xanxia dosage is moderate to none

• A little bit of Wuxia is ok, but xianxia is not my style. These overblown exaggerated evil characters, combat skills where its not even a combat anymore just them doing some lightshow with their hands is not my cup of tea.

Dialogue

• Characters develop inside jokes which makes everything more authentic
• FL and ML have amazing chemistry, the way they resolve conflict is interesting, the way they fall in love, talk about situations in life, they have rizz.

Supporting Characters

• Main antagonists have background story, good sides, you don't wanna fast forward their scenes, you watch them too. 
• Other supporting characters have some rizz, they bring up feelings to the story not just boring dialogues of palace intrigue or completely illogical love interest where FL and ML give them no attention at all but somehow they go irrationally crazy about them.
